I purchased and used my OTTO back in June of 2018. About a week ago, for no reason, the thing completely broke. Would not start, grind, turn on or off. I contacted OTTOMATION and within 10 days received a brand new unit.I wanted to highly recommend the customer service of this company. Rest assured if you have a problem, they will take care of it no problems asked. Now on to the review...I love the simplicity and modernity of having this machine. It does do the job well, but like some of the other comments here, could use some improvement in future models. You have to remember this is a brand new product, and like with anything new, there are some bumps along the road.PROS: Nice design, easy to use, charges quickly, (somewhat) easy to cleanCONS: Cleaning the actual unit itself can be laborious, esp. depending on the stickiness of the flowerAlthough honestly more of a novelty at this point, it does bring a new simplicity to rolling your own, and would recommend to any cannoisseur out there who appreciates a well made cone!

This is my third review. I've had it for Less Than 3 months and it stopped working. It makes a loud winding slash screeching noise and does not move the grinding mechanism. I'm still well within the one-year warranty. But outside of the one month return. Amazon told me to contact banana Bros through amazon. I contacted them and they wanted a picture of my device which I posted. From that point on I've never heard from them. Very very sad customer service. Amazon had to step in and make it right. Would still cost me a restocking fee but at least I'm not down 160 bucks in total. When the machine was working it was the best automatic grinder I found. But for 160 bucks in the last Less Than 3 months that's ridiculous. Far from the best. So do not buy!I needed this grinder because I had hand surgery. The first one I purchased constantly shut off for no reason. I found out that the rod was that long enough to fully close the limit switch so the grinder knows it's closed. Clearly if all the unit so I returned it. My new grinder works much better but still has its issues. The stuff I'm grinding up is usually a little bit dense. I'll put a nickel size bud in the grinder and there's times the unit cannot handle it. It will try for a bit and then shut off. You either have to wait a minute or two to turn back on or plug in the power cord real quick and unplug it and then you can finish grinding that piece. There's times I put two of them in there and it works fine. They definitely need a bigger battery and probably a stronger motor. And it uses a micro usb to charge. It should definitely be a type-c. I lowered it to three stars because the batteries charge is getting worse.

Now to my review of the auto roller. I’ll start with the good then to the bad.The good.:It rolls joints:Supper high quality moldings on the plastics with a nice anti stick almost soft plastic texture. That part is expensive to manufacture so big points to that. The fit finish alone makes me know this is not a cheap item.:It’s a well thought out unit. (See the pic with this text). In the open position the hinge is maxed open but rests perfectly on the table like dead nuts perfect. Again making it feel like it’s a premium product.:I’ve ran around 1/3 ounce through it and it’s to the point it needs to be cleaned. Still works fine so points.:I’ve never had to unclog it or have it not grind all the bud.:The preprogrammed grinding sequence it does is very smart. Almost makes you think it’s getting feed back and changing how it grinds based on load…not the case but still points for making me think that’s a possibilityThe bad.:Battery life is not the best you get around 6-10 joints per charge over 2-3 days in my experience. Not terrible but not great.:It does not work while plugged in and charging. I’m going to go on a rant on this topic but it’s pretty unacceptable for any DC product to not work while plugged in and charging. It’s a $0.03 one way mosfet to add that functionality.:It uses a micro usb as the charging port. It’s 2025 and we got Apple to use type c. Everything should be type c.
