After trying several ergonomic wireless mice, this is easily my favorite thus far. My hands are relatively small and was previously using the PERIMICE-719, but the angle on this 804 relieves a lot more tension off my forearm and wrist.The bluetooth has been flawless and battery life has held up. The sleep timers and wake function are responsive and do not cause inconvenient interruptions during use.I still use a performance mouse for gaming and precision work, but try to find any opportunity to

I'll be honest, I like the feel, ergonomics, and mouse overall.The part that they screwed up is quality control of the mouse scroll wheel. It will be fine initially but after a little bit of use, the wheel goes loose and you cant get proper scrolls. Sometimes when you're going down, it will go up a couple times then down again, and vice versa when going up.For that, I gave it 2 stars because scrolling is an essential function of a mouse. If the scroll wheel worked or got fixed, I would give it…

I love the mouse. Especially the thumb grip lines, makes holding the mouse easy. ( Anker doesnt have the grip lines) I dont like the 2 buttons RIGHT where my thumb tends to lift up. If they were a tad higher (like on the Anker vertical mouse) id love it. I suppose if i actually used those buttons, i may find them helpful. but i dont so they get in my way.

I absolutely love this! I have the expensive Evoluent and I do like it, but I use it at home and wanted a cheaper one for work. This thing is just as good to me as the Evoluent. I actually like the buttons better because you can clearly press them and it clicks. It's comfortable and really helps with the joint pain. I do have feminine hands, so I'm not sure how this would work with larger hands, but it is perfect for me and I have recommended it to co-workers.

This is my favorite mouse, after using a whole bunch of ergonomic mice, including several years with Evoluent. The nice thing about the wired connection is that, no matter what machine, computer I use, the wireless connection is just unstable. I needed to be really near the transceiver to get reliable tracking, and after buying 4 wireless versions of this, I got so fed up with inconsistent performance, I bought 4 wired version. So yes, they have wires, but they work well, are light, I control…

If it weren't for the annoying blue LED light on the left side, this would be a pretty nice mouse. The pictures and description don't indicate that the blue light is there, and it is VERY bright. It even stays on after shutting off the computer. I'm not sure how that can even happen, but it does. Why do manufacturers feel the need to add cosmetic lights to their products?

Very comfortable and works well. The angle of the mouse is perfect to fit in a natural position for the wrist.not too vertical and not too horizontal. The slightly rubberized surface feels nice and provides good grip of the mouse. Battery life is quite good and is one of the longer lasting Bluetooth mice I've used

Mouse is ergonomic and vertical hand grip definitely eliminates palm pain. Rubberized parts of mice is nice and have nice feel. However, button are not sensitive enough so when you click the mouse botton, the mouse moves left. This is quite annoying and caused me to retire this mouse. I used it for couple months at work so I have over 300 hours of use on this mouse contrary to many users who posted their reviews after using it for 5 minutes. I will sell it for sure because this mouse is not a…

So far fantastic. If things go downhill, I'll update the review.This one replaced another ergonomic mouse (see my other reviews) that's right click button was so sensitive it clicked even when you didn't want it to. And after a month of use, scroller broke. THIS ONE, on the other hand feels like a better made product. Even the box it came in was of better quality.it's sleek, looks modern and stylish and fits my hand nicely. It takes only a few days to feel comfortable using. Scroll mechanism is

I use a mouse for at least 8-9 hours a day at my work and this one is amazingly comfortable! Wish it had been around 8 years ago when I broke my right wrist.

The design of this mouse is great. Unfortunately, I have tiny hands (size 7.5) and stubby fingers, and this mouse is just too big for me, making it challenging to hold it comfortably. Which means it'll be perfectly comfortable for standard-sized hands. The indent for the thumb is nicely ridged for grabby power, and the outside is smooth and makes it easy to click and scroll; gliding across the mousepad is very smooth, and the mouse is very sensitive and responsive. Despite special adjustments…

My husband has been having hand/wrist problems. This was great after he had carpal tunnel surgery. Put his wrist at the right angle.

I bought this item open-box for $8. For that price, I couldn't be happier. It is comfortable, buttons click nicely and the scroll wheel is smooth. Fits my needs nicely. It was not difficult to get used to the angle of the mouse, and I can hold it comfortably even though my large hands are used to a fingertip/claw grip with regular sized mice.

I bought this mouse as I was having extreme wrist pain with the standards type. This one did the job and is easy and comfortable to use.

Its new design (over the Perimice 608) fits better then ever. Nice feeling, precise, comfortable. The soft coat on my 608 got worn out in places, however it lasted 2 years under heavy use (that's the 4 stars). Fully recommended, specially por designers, engineers and architects who spend many hours working on the screen with a mouse.
