Summary: The wheel lost its functionality after using it for about 4 months. I had been a happy customer until then. Without functional wheel, I felt like a caveman trying to move my cursor to the right of the screen and scrolling.
It would have been 5 stars...until it stopped working

Summary: I'm not sure what the deal is but there are enough reviews here to let me know that quality control seems to be an issue with these things. Mine stopped after several months. When it does work it's an effective product, the tilt feature was quite good in relieving stress on my wrist. It looks like somewhere in their production line they went with a defective or cheap part that seems to result in a higher than acceptable rate of failure. Too bad it's a very good idea.
Summary: I bought this mouse because my wrist was started to become irritated from being stationary. I picked up this little mouse and loved it. The motion was much better, not to mention it was sorta fun to see the reactions from other people when they attempted to use it and realized what it was. The battery life was good and it did what it was supposed to. Gradually it started having issues - you had to REALLY mash down the left click to get it to respond.
Summary: This is my second Smartfish mouse which I readily bought (very comfortable) when I thought (stress that word) my wheel had stripped on the first one from use over the years now, however.... when the second one arrived, brand new out of the box, I found out that it had the same issue: the wheel moves randomly or... not at all? It's best described as erratic to the point I don't use it (can't)...
Summary: after one month of occasional use- it just quit working. not a dead battery issue (tried new batteries) just quit. I have the full size version in my home office and it has worked great for over a year now with no problems. Either the mini version is just a bad design; or I got a lemon. ???
Summary: I bought one of these for my office and it really worked. My wrist pain is gone. As a result I bought a second one for use at home. The second one did not work from the start. I tried everything to get it to work including uninstalling and re-installing the driver, synching and re-synching it with the receiver, using a different receiver. I checked blogs on this and could find nothing to help.
Summary: I have a very small hand/wrist and suffer from wrist and hand pain when using most mice for over 15 minutes. This mouse has a spring-action effect to keep your wrist at a comfortable angle, which has helped my pain level a lot. It fits my small hand well. The only reason I am giving it 4 stars is that it feels a bit flimsy and I am not sure if it will hold up with time, but so far so good.
Summary: First off, this helped tremendously with my wrist pain. I can put in a solid day of work with little to no pain. That said, this mouse has some serious issues which have me shopping for an alternative. First, the receiver is terrible. I've used wireless mice from Microsoft and Logitech that would work perfectly through obstacles, but putting a metal object anywhere close to the receiver will render the mouse unusable.
