I love this mouse so much! I really wanted something that I didn't have to use on a flat surface like a standard mouse. For work I regularly use a program that is keystroke driven and this mouse makes it possible for me to type short key sequences without having to put my mouse down or move my arm away from my keyboard. The trackball is very responsive on screen and works smoothly. I really like having scroll, left click, right click and enter keys all in one hand. The best part is the flexibility of being able to use the mouse from any location. My mouse hand used to get very cold while using a standard mouse where I had to keep my arm in one place for so long. With this mouse I can rest my hand and arm in any location. Being able to drop my hand down in my lap but still continue to work is fantastic! The position of my hand and wrist ( and shoulder) is so much more comfortable and natural! Cold day? This thing works from under a blanket which is perfect for online shopping, reading or streaming. Not sitting at your desk? No need to balance this mouse on your leg or on the arm of the chair - set it down anywhere or keep holding it while you type a little! After using it for one year, the main drawback I've had is occasional non-responsiveness. At first I thought it was eating batteries, but that's not the case. It just seems to stop communicating with the computer. I'd say that 80% of the time I can fix that by turning the mouse off and back on, which is quick and easy with the exterior switch. 10% of the time I simply unplug the USB dongle from my laptop, plug it back in and it gets back to working just fine. The other 10% of the time the batteries are just dead or dying. The non-responsiveness issue happens at least once a month - I use this product 5 days per week, 10 hours per day and don't find this issue to be a major detractor at all. If this thing died today I would buy another one without hesitation. The design really works for me (I don't have exceptionally small or large hands). Perhaps if I had really large hands this might not work as well, but that's not my experience, so I really can't say for sure. If you are a road warrior for your job, you may really love this gadget - no flat surface required, skip the laptop touch pad, no laser light shooting out of the mouse when it's tipped over, fits in a cup holder too. It won't pack as small as a travel mouse in your laptop bag, but it's fine. If your are having sore shoulder, wrist or numb hand, this mouse might be just the relief you need. Read more

Working well. The ball takes some getting used to. I wouldn't use this for gaming because the ball is hard to use precisely, but it's great for scrolling the web, copying and pasting, kindle or pdf reading on the computer, etc. the enter and escape buttons on it make it even more ergonomic, since I don't need to reach out and use my keyboard unless I need to type words. My right shoulder, arm, and wrist were extremely sore from scrolling through pdfs for classes for hours. I've experienced a lot of relief from this. Can relax my arms wherever, in my lap, etc, and scroll in comfort. Easy to use in either hand, even for someone as extremely right handed as I am. Also, I keep accidentally knocking it onto the ground bc I'm clumsy (this happens with all of my objects, so I wouldn't know if the design makes that more likely or not). The battery cover part pops off when this happens. But it goes back on fine, doesn't break, and works the same. So I'd say it's fairly hardy. eta: so I meant to submit this 6 months ago. I'm still using this mouse without issues. If it stops working, it normally just means the battery needs to be replaced. Occasionally I'll need to unplug and replug the usb- but this is after I've had it plugged in and shut and opened my computer multiple times, sometimes over a period of days. Been using this mouse for over a year and it's still going strong and getting much more intuitive. Also no longer have issues with accidentally dropping it. Read more

UPDATE 4/3/23 I have two of these and have now used them for a couple of years, and they've gotten even worse. On one the thumb wheel stopped working. On the other one the main problem is that it deactivates within a few seconds and then I have to push one of the buttons to reactivate it. It used to go several minutes before deactivating. The trigger switch (left mouse click) is also getting flaky and often does not make contact. Maybe the newer ones work better, but the ones I have seem to have been made with the cheapest possible components. My two units were purchased several months apart, so it's not just one bad batch. Having both develop problems is remarkable, and makes quality look pretty bad. ORIGINAL REVIEW It works OK as a remote control for watching YouTube videos, but it constantly deactivates, and I have to push a top button on it to reactivate it, and then it works for a few more minutes. It deactivates when it sits idle for six minutes, which happens each time I watch a video. I have been using it for a couple of weeks now, and the need to constantly reactivate it has become a huge annoyance. I'm very tired of it and I'm sorry I ordered it. Aside from the deactivation problem, it works well for YouTube, and it can be used from the other side of the room just fine, but it does not work for anything else. Operating it with one hand for normal computer use is almost impossible, so I don't use it for that. When I watch videos, I use both hands to operate it, and I'm OK with that. I have a second, older one of these units that I got a year ago, and it does not have this six minute deactivation feature, but yet has satisfactory battery life. But on the other hand, that old unit has a problem that was fixed in the new one, the speed at which the pointer moves. On the old one, the pointer moves too fast, even at the slowest setting, but on the new one, it moves at a comfortable speed. So it appears that the manufacturer keeps tweaking the firmware in this thing, but has no sense of how to make it convenient and pleasant to use. That's unfortunate, because it really could be a good product if they would just set up the firmware correctly. There is also a mechanical problem...how the trackball works. There's something about it that makes it tedious to get the pointer precisely to where you need it. That's OK for YouTube because the thumbnails are big, I'm using both hands, and I only have to select a new video once every few minutes. But it's very difficult to use it for anything other than YouTube, so I would not try to use it for any serious type of work. I would return it, but in my area to do a return I have to drive several miles to a store where I can take the return package, and that's very inconvenient for me. Read more
