Logitech M570 Trackman™ Wireless Trackball Mouse, 2.4GHz with Unifying USB-Receiver, Scroll Wheel, Programmable Buttons, 18-Month Battery Life, PC / Mac / Laptop

This is a robust, versatile and comfortable mouse Major features for me - better build than Microsoft - comfort and versatility in use - unifying receiver - excellent battery life I've had used umpteen devices since my first pc over 20 years ago. I currently use a laptop and have 2 mice and a keyboard running faultlessly from 1 unifying receiver (M570 trackball, Performance MX mouse, and K360 keyboard). The M570 withstands everything I throw at it - the trackball is securely held in its socket and comes out with gentle coaxing when you eventually need to clean the three mini rollers that hold it in place. I have been very clumsy with this mouse and dropped it on the floor on more times than I remember (more than 20 in over 3 years of use). The mouse has hit the wooden floor with enough force for the trackball to bounce out - but I just put it back in and it is still working perfectly. I have found in general that Logitech mice have better longevity in use. Compared to the Performance MX mouse (which sits on my desk and has different functions assigned to its buttons - done easily with Logitech's software) it is a superior product for comfort and ease of use. The MX may track on glass; but it still requires a surface to operate on and much greater wrist / arm movement to use. The M570 is just easier and more comfortable. Logitech could improve the product by adding the functionality the MX has with scrolling (a button that enables free scrolling). They could also add extra thumb buttons adjacent to the trackball to increase versatility. There are two problems with the mouse : They do not make a left handed version (serious problem for lefties). You have to get used to using your thumb (water off a ducks back with practice).

I've had a previous version of the this - a Cordless Trackman Wheel for many years, but recently I made the mistake of putting a cheap battery in it, which leaked and killed it. I was so impressed with the long term reliability of the previous device that when I was looking for a replacement I felt compelled to go for this updated model rather than a different brand or style. I bought it from Pomegranate, with delivery to an Amazon Locker, and it arrived swiftly, brand new, as described. The M570 has lived up to my expectations completely. It's very comfortable, accurate, and feels as durable as my previous version, so I'm confident it will also last for many years. I haven't installed any additional software, just plugged in the discreet USB receiver, and let Windows do the rest. I just use it for the basic functions - moving the cursor, left and right clicking, and scrolling through documents with the wheel. This means the additional buttons (initially programmed for moving the page forward and back while web browsing) are superfluous for me at present, but maybe I'll try making use of them in the future. I've also made no attempt to re-program any buttons, as I've read is possible, maybe with additional software (not included - I assume that's something to download from Logitech). I love the freedom you get from a trackball device. I don't need to worry about what surface I'm going to use, so I can easily move my laptop to a desk, an armchair or even my bed, and not bother about an additional surface to roll a mouse around on. I think that for my purposes - mostly web browsing, document writing and programming - a trackball is ideal. If you are interested in certain games, or other uses that require faster movement around the screen, this is probably not going to suit you, but I can quickly and easily navigate around an extended desktop with no problem at all. Some general points: It comes with a battery (Duracell AA) already fitted and ready to use when you remove the plastic protection tab. It has an on/off switch, unlike my previous Trackman, and that device lasted for months on a single battery so I have high hopes that this will be even more efficient. There's also a little light that briefly flashes green when you switch it on, and I believe it will flash red when the battery is low. Finally, the USB receiver is discreet, as I mentioned before, with less than a centimetre protruding from the socket. You can keep it plugged in and still carry the laptop around with you quite easily, but if you want to remove it for any reason, there is a little slot for it in the battery compartment so that you can avoid the risk of misplacing it. I've been using the M570 for a couple of weeks now and I haven't had a single negative experience. I recommend it wholeheartedly.

It's a trackerball mouse. The ball moves, the mouse stays put. Mine is part of my gaming rig, stuck to the side of my chair, where it falls easily to hand. In flight sims it's fun to fly keyboard free- I use pedals, a throttle, a high end joystick and now the trackerball. The ball allows me to select controls within the cockpit that I'd otherwise have to assign keyboard shortcuts to. It's very satisfying to look at a knob or lever and just adjust it on the fly, rather than having to memorise dozens of key strokes to achieve the same thing. It adds to the sense of immersion as well as easing my workload. It works particularly well with head tracking software and VR goggles. As a mouse it's fairly intuitive and will do pretty much everything a regular mouse does. It's worth considering if you have limited desk space or if you're carrying old injuries. My wrist was broken some years ago and I find it much more comfortable than the conventional mouse I have to use in work. I've given the 'battery life' five stars. That might change, the device is brand new! But I'm typing this on a Logitech keyboard and I've used wireless Logitech mice for years. They've all had excellent battery life, I don't see any reason why the trackerball would be any different. If the device does have any problems over the coming years I'll update this review. If there aren't any updates, you can take it that everything worked out just fine for me and my new purchase. Tl;dr. Good product, ideal for my needs.

Cela fait quelques mois que je m'intéressais aux boules de contrôle (trackball) pour remplacer ma souris, et j'ai fini par choisir ce modèle. Aucun regret jusqu'à présent, la prise en main a été ultra-rapide (à peine 15mn !), quoique mon pouce a encore tendance à réaliser des mouvements trop brutaux pour les déplacements latéraux. Il est important de manipuler la boule du bout du pouce, zone la plus précise, et sans exercer la moindre pression dessus. Parmi les avantages, je note : - la réduction de la fatigue musculaire à l'arrière de l'épaule, ce qui est un vrai plus quand on passe beaucoup de temps devant l'écran (10 à 14h par jour dans mon cas, à mon compte dans l'informatique) - une rapidité et une précision accrue une fois la boule prise en main. Je le note particulièrement dans la manipulation des fenêtres, que je déplace d'un bureau virtuel à l'autre en bougeant à peine le pouce, et dans la vitesse des copier-coller (sélection presque instantanée de la ligne ou paragraphe) - c'est propre et ça prend peu de place, surtout visible après que j'ai eu débranché le socle, l'adaptateur, et le cordon USB de mon ancienne MX1000 - pas de pilote nécessaires contrairement à la Marble de la même marque. Testé sans le moindre problème sous Windows 7 et Ubuntu 14.04. - et enfin de manière particulièrement subjective, c'est une interface plus agréable que la souris d'un point de vue sensoriel. Le trackball épouse bien la forme de la main sans en bouger, et la sensation de la boule qui roule sous le pouce est assez agréable. En comparaison, la souris que l'on agite de partout frotte, déboîte l'épaule, fatigue, et donne une impression de lutter avec la machine une fois qu'on a essayé le trackball. Pour les reproches : la roulette, que je trouve trop dure tant pour le défilement que le clic du milieu... elle donne l'impression d'être prise dans le plastique. Les matériaux sont corrects sans non plus êtres extraordinaires, 100% plastique, pas la peine de chercher du métal ou quoi que ce soit de plus noble. Pour 40€, on aurait pu attendre mieux, mais hélas les trackballs sont un marché limité avec très peu de concurrence, ça n'aide pas à garder des prix bas. La qualité de finition est bonne, pas de jeux dans l'assemblage ou de boutons qui "flottent". J'ai lu ici et là que les contacts de pression peuvent se dégrader avec le temps (plusieurs années), mais ce n'est pas propre à Logitech ni aux trackballs donc j'attends de voir avant de me prononcer. Dernière recommandation, la boule doit rouler librement dans son support, avec une légère inertie et sans rencontrer la moindre résistance. Mon modèle sorti d'usine frottait légèrement (friction audible), ce qui semble malheureusement souvent le cas. Solution : sortir la boule de son logement et gratter légèrement le pourtour du logement en prenant soin de ne pas toucher les roulements à bille et le capteur. Personnellement, j'ai utilisé la lime de mon coupe ongle pour enlever ces aspérités de démoulage. Depuis, elle roule à merveille, sans frottement ni résistance. Au final, je laisse 5 étoiles plutôt que 4 car je suis vraiment satisfait, je ne reviendrai pas à la souris et les reproches envers ce trackball sont plus des bémols que de vrais défauts. N'hésitez pas à essayer celle d'un collègue ou d'un ami si vous travaillez beaucoup sur ordi, même si vous ne parvenez pas à être plus précis qu'à la souris, vous devriez au moins gagner en confort d'utilisation.

Dopo averlo provato intensamente per più di 2 mesi, posso dire che è un prodotto eccezionale!! Il primo giorno è stato un disastro, l'abitudine al mouse ha destato molti sospetti su questo trackball, ma durante la prima settimana d'utilizzo è stato abbastanza strano il dover usare il pollice invece dell'interno polso per spostare il cursore, ma a forza di lavorarci (sopratutto in programmi di grafica 3d) si è rivelato davvero indispensabile. Addirittura la mia ragazza che lo ha utilizzato un paio di volte alla settimana, ormai lo padroneggia con disinvoltura! Inoltre, a livello fisico, ho riscontrato un minor affaticamento della spalla/braccio, ed una posizione più naturale sulla sedia. Il pulsante centrale ed i 2 pulsantini a lato sono totalmente configurabili, in modo da adattarsi ancor meglio al nostro stile di utilizzo, inoltre è presente un LEd di stato per la batteria. Nella parte bassa, è invece presente un interruttore per poterlo spegnere e limitare così i consumi della batteria, inoltre questo traskball è dotato di risparmio energetico , ed infatti da circa 2 mesi non ho ancora cambiato la batteria AA in dotazione della duracel. All'interno del vano batteria è possibile anche riporre il ricevitore unify, in modo da poterselo portare comodamente senza perderlo. La sfera blu, è estraibile con una pressione dal fondo in cui è presente un foro, ed è possibile pulire l'intercapedine di alloggio della sfera, il quale forse è l'unico punto dolente. Infatti si sporca di pelle morta abbastanza frequentemente, quindi è da pulire spesso almeno una volta a settimana. Che dire, come grafico ed utente avanzato lo consiglio a chiunque, per quanto riguarda il mouse, potrebbe benissimo estinguersi.

I've been using Logitech trackballs since... OMG THAT LONG! Sept 1994 I went for an interview at a company for my first job in computer graphics - in this case label design. The owner sat me down at a desk with a trackball. What the hell is this thing? Needless to say I loved it and have been using a trackball ever since. Quite honestly I'd trade this USB version back to a corded one if I could still get it. At my desk it really doesn't matter and nothing worse than the couple days prior to your battery actually dying. LONG LIVE THE LOGI TRACKBALL!

Wer sich von der traditionellen Maus einmal auf einen Trackball umgewöhnt hat, wird vermutlich nie mehr zur Maus zurückkehren wollen. Keine Probleme mehr im Handgelenk (abgeknickte Haltung beim Bewegen der Maus), keine Untergrundprobleme (z.B. Glastischfläche), sehr zügige Cursorbewegungen (Daumenbewegung ist schneller als die gesamte Hand) und natürlich die minimale notwendige Grundfläche sind in der Summe gewichtige Vorteile ggü. der konventionellen Maus. So kann ich den Trackball auch bequem auf dem Bein ablegen und trotzdem vernünftig den Cursor bewegen. Hilfreich können auch die Zusatztasten sein, die aber auch häufig die üblichen Mäuse bereitstellen. Die Kugel (Trackball) ist sehr leicht zu bewegen. Im Bedarfsfall kann sie leicht werkzeuglos entnommen werden und gereinigt werden (wie auch die Trackballaufnahme). Der zugehörige USB-Stecker ist schön klein und findet bei Nichtgebrauch Platz in der Maus. Schön auch der niedrige Stromverbrauch. Bei mir hält eine Batterie jeweils über 2 Jahre (bei täglicher Nutzung)! Der Trackball geht automatisch nach einiger Zeit in den Standby-Modus, aus dem er bei Bewegung sofort wieder erwacht. Zudem lässt sich der Trackball aber auch ganz ausschalten. Das nutze ich aber normalerweise nicht, weil nur durch die Standbyautomatik schon die oben beschriebenen 2 Jahre (und mehr) erreicht werden. Die Ergonomie ist zumindest für meine Hand gut geeignet. Die Hand liegt entspannt auf dem Trackball. Orthopädische Probleme habe ich durch die Trackballnutzung bisher keine bekommen.

De batterijen gaan lang mee, zelfs bij dagelijks en langdurig gebruik. Knoppen en trackball reageren goed, nu reeds jaren in gebruik. Tevens makkelijk te reinigen door de bal er uit te drukken. Ook een voor mijn zoon gekocht.
