It is very comfortable to use
I gave it 4 out of 5 stars
This Splaks 2.4Ghz wireless optical mouse is so much more comfortable than my normal mouse. I like how the thumb area is sunken in. It makes my hand much more comfortable. This mouse looks better and seems to work better than my other mouse did. This mouse uses 1 AA battery. This mouse looks nice and has extra buttons in the thumb area, a forward and back button. In between the right and left clickers is a button to press to choose a DPI setting. I think that is nice because it saves me from a lot of unnecessary movement. There is one little peeve I have and that is that the right and left click buttons are not quiet at all. If this was a quiet mouse it would be PERFECT. Even with that issue, I still think the mouse is very comfortable and I really like it. I received this item for free to try in exchange for my honest and unbiased review.
