I have big hands and I was using a regular sized "normal" mouse, but developed an ache in my right index finger knuckle. The ache became a pain and I had to stop using the mouse and rest for a couple of days. I bought this mouse and it's been great. The grip is very neutral and feels like a glove-type fit. The mouse itself has a very good velvet feeling to it and the buttons are in the right place. The only downside is that it is tall, so initially I would knock it over as I moved my hands around the desk area. I must have become used to it though because it doesn't happen that much any more.

I've had my mouse for a little over a week now and I absolutely love it. Over the past few years I've started to pay close attention to how continual computer use is affecting my hands, wrists, and posture. I wasn't in any pain before purchasing the mouse, but a normal mouse forced my hand into an unnatural position. This mouse allows me to keep a much more neutral hand position while limiting wrist bending. For best results with this type of mouse, your hand needs to be suspended above the desk surface.

This mouse is awesome! I got this because I started to develop a tender wrist from pronation/supination of my wrist. Wow, did this help fix the issues! This mouse is very comfortable and has buttons in the right places for easy access. I use this mouse for home and office use. The mouse is always accurately sensitive, so you get exactly what you expect in terms of mouse speed and mouse precision. There's a few minute learning curve of getting used to "aiming" with the mouse but is quickly overcome with > 1hr of play.

I bought this mouse to relieve strain/pair/pain in my forearm. It's pretty good. I prefer this mouse to the similar Cherry ergonomic mouse. The Cherry is too thick, making it feel really unnatural. This mouse is a bit thinner at the fingertips, making it feel a bit more like holding a pen. This makes it feel more natural and easier to use more precisely.

I was skeptical, but I wanted to try it out. After playing games, I noticed myself resting by holding my regular mouse in almost the same position. Seemed only natural to try out a mouse that does this by default. It may not replace your gaming mouse, but for everyday things it's pretty comforting.

The learning curve is pretty low, it's very comfortable to use. I do a lot of computer work because I work from home and I have to say my hands don't seem to get tired as much. Also the light looks super cool especially with my backlit keyboard.

I bought this after reading a review that said once you get used to it, it's a good mouse. I didn't have to get used to it at all. It felt perfectly normal immediately. I'm not sure I ever want to go back to a horizontal mouse again.

My only gripe that keeps this mouse from earning 5 stars is that the cord is shorter than the one from the previous mouse I had. If the cord was longer, this mouse would be perfect.

I find the mouse very comfortable, and it isn't too difficult to press any of the buttons. I like that it has two additional buttons near the thumb. The material is a nice matte finish.

My only negatives would be that my hand gets slightly sweatier using this mouse than a standard mouse

I hadn't realized how sore I got working on the computer all day until trying this.

I am so happy with this mouse!!!! I could gush about it for ages!!

I’m not satisfied with the scroll wheel on this mouse.

Highly recommend this item for everyday use.

I don't like the way that this feels in my hand!
