Very happy with this mouse. Seems to charge fast and plenty of options for mouse buttons. Easy to install and very comfortable to use. Also has Bluetooth support which not many have at this price.

Definitely worth the price!At first, it might not feel very comfortable, but give it a couple of days, after that, regular mice actually start to feel uncomfortable.It’s perfect for daily tasks, especially for designers.To be honest, I even enjoy using it for gaming! It could be a bit larger for bigger hands like mine, but overall, it works great.I really like it!

This has worked great. My only gripe is that it doesn't warn me when the battery is low. When it was super low, it stuck on scroll left. I had to disconnect and re-install after charging to fix the issue. Otherwise, the respond time and ease are great! I would recommend but set a reminder to charge regularly since this will not warn you.

Very comfortable to use and connected instantly with my iPad!

The functions work perfectly and the vertical angle is perfect. My hands are too small, but its good for my bf who has really big hands and always needs bigger tools

I wanted to see if this was a worthy substitute for a similar, name-brand mouse of the same type. The form factor is the same and it works, but that is it. I tried a couple of these after reading reviews that said people had hit or miss experiences. I was hoping one out of three would be a home run. I sit in front of a computer for 10 -12 hours a day and I have started to develop serious carpal tunnel in my right hand and wrist. My doctor encouraged me to find tools that will help me continue to work while not destroying my body. I have the name brand ergo mouse and tried out this one and a few others. Darn it, the name band works better for me. It is heavier. That makes it easier for me to do fine mousing work. The name brand also is also more comfortable in my hand. I tried the smaller and larger versions of ergo mice. I don't have big hand, but the bigger version is so much more comfortable and easy to use. I might hang onto one of these as a backup.Update - the mouse stopped working when I paused work. Like I walked away for an hour and the mouse did not work. By turning it off and back on it started working again. But any significant pause in work made the mouse stop working. Not a fatal flaw, but kind of a pain.

It's a very good product. It feels good to the touch. It has excellent responsiveness. The ability to connect to three devices gives this mouse an incredible advantage.Plus, the battery lasts quite a while. I've only been using it for over a month and have only charged it once.

I have Med-Large hands which I think is important to remember when you read this review. Hand size is very important when you're considering vertical mice. For me, I switched to vertical mice due to carpal tunnel a couple years ago, and it really helped to eliminate it. I went to Best Buy and tried both the Logitech Lift and MX Vertical. The Lift is for smaller hands and I didn't like the feel of it. So I bought the larger MX Vertical despite the $100 pricetag with the hope that it'd help my carpal tunnel. It did, but unfortunately, now its suffering from the double click issue that apparently is a feature of Logitech mice. So I began the hunt for another vertical mouse that didn't cost +$100. I knew I wanted one that was for Medium to Large hands, so I’ve tried 5 different ones that said they were for larger hands or had similar measurements to the MX Vertical. For reference the dimensions shown on box are 4.8in x 3in x 3.1inPros: Mouse is definitely larger and fits my hand nicely. The bubble shape fills my palm nicely. The clicks are quiet and soft yet tactile. Scroll wheel feels fine and not flimsy. Has a rechargeable battery (which technically is a con if it quits working). Price was very competitive at $17. The DPI goes to 2400.Cons: The bottom “slip” pads sometimes catch on my mouse pad. The clicks aren’t as satisfying as the ProtoArc EM11 or Nulea M510 and I definitely like the scroll wheel better on the M510.In the end, I will probably keep this one as my replacement for the MX Vertical. Even if the mouse might be somewhat inferior, $17 vs $117 is too big of a price difference to ignore. And for me at least, the shape is the best fit for my large hands. I will say that I tend to agree with the other reviewer that the Nulea M510 is an upgrade to this mouse. The clicks are better and the scroll wheel is nicer. However, it is shaped differently with a curve and less of a bubble shape and more of a gentle slope. For me at least with the M510, my hand tended to slide down the slope and end up resting on the mouse pad which so far doesn’t seem to happen with this one. Is it perfect? No. Will it work for me without breaking the bank? Definitely.
