Quality:Made from solid ~5mm aluminium and steel. High manufacturing standards - no sharp edges, no chips in paintwork, no play in any of the multiple joints, hinges or connectors. Integrated cable tidy fits my very thick DVI lead and power cable. Clamps very securely and firmly. Mine is supporting a 23" LCD.Functionality:Highly adjustable in every plane.Main strut allows ~25cm of vertical adjustment, plus probably the same again in the second arm.If you leave enough play in your cables, you can easily spin your monitor through 360°.Both tilt and second arm can be adjusted for resistance to suit the weight of your monitor. Once you tune this in, you just grab your screen, put it where you want it, and it stays exactly there until you move it again.Screen can tilt over 90°.Very easy to grab your screen and rotate it to portrait. Excellent for working with long lists of data.Clamp can accommodate a desk around 10cm thick.Value:After spending two weeks using a workstation in one of our US offices that was equipped with a similar monitor arm, I knew I had to have one at home. I was looking at mounts with identical functionality from other manufacturers for anything up to £200. Having used a mount for a fortnight that I know retails for >$250, I can make a direct comparison. The Duronic is just as good. The Duronic is a quarter of the price.

It's a great product that's easy to put together and allows for a great deal of freedom when moving my monitor depending on what I'm using it for. For this price it's difficult to complain.The model I received was faulty, though. The main mount that holds the monitor had no tension do it kept drooping under the weight of the display. After contacting customer support and reassuring them that I had tried to adjust the tension according to the instructions they send out a replacement part that took all of ten minutes to swap out. Their customer service department deserves credit for this as all in all there was less than a week from my first email to receiving the new mount.

I bought this for an Asus 23 inch monitor I use, the VE247. At first I was dubious putting this together, with it being on a spring I didn't think the monitor would hold up well, but it did. After tucking 3 cables under it, the DVI, HDMI, and power cables, making sure they had some slack so they wouldn't tug when the arm was fully stretched, the setup was complete. I can swivel any way I want, stick in portrait mode and all that lovely stuff and it holds up perfectly. I've been using this for 2 months and I haven't had any issues so far and I move the arm into multiple positions several times daily (I like to stretch it out towards my bed when I watch my anime, then back for gaming). 2 thumbs up, highly recommend this one.

A fairly decent quality monitor stand and would highly recommend to anyone.The reason why Ive not given this 5 stars is because I have previously purchased the Duronic DM451X3 Solid Single Solid Arm which had a rubber insert, which sits on the desk and helps the arm to stay in place, this particular arm only has plastic on the base, and no sign of any rubber padding in the box. Consequently the arm has a tendency to move slightly.

Great piece of kit, the only things I didn't like are the:* price* the difficulty I had with tightening one of the screws hard enough to keep the vertical tilt of the monitor up so that it would face me and not the floor. I had to reverse the washer where one side was deliberately "rough" which was the "edge" that did it for me. I still worry about this when adjusting it though.

The product entirely makes sense and makes my life as a website administrator/developer a million times easier with my 27" screen on this. Only downfall was that the bolt which tilts the VESA mount was rubbish and didn't hold the screen upright - I replaced this with a regular nut/bolt so it could be tightened and works fine.

Great value for money. Easy to install. My dual monitor set-up looks posh and professional. Both monitors are highly maneuverable. For my heavy 27" Dell all I had to do was tighten the tension spring and it works just as well as lighter Asus swift. Was worried about wobble as I have a heavy goods rail line 20 metres away, can gladly say there is no movement at all, unless you choose too. Only time will tell on how durable they are.

For the most part this is an excellent arm, giving good movement at a reasonable price. It has a weakness, though; the adjustment for the monitor tilt isn't robust enough to take the weight of a monitor, so you end up with the monitor looking downwards at the desk. The joint immediately behind the star mounting point is the issue. Rather than returning these otherwise excellent arms I've bodged them by adding small blocks of wood with screws to act as a prop to support the monitor in the desired position.
