Summary: Nice basic laser mouse, works well. The feet are a different material than on gaming mice; do yourself a favor and stick some "slippery tape" on the feet for smoother, and quieter, operation. http://www.leevalley.com/en/wood/page.aspx?
Summary: Goes well with my washable Logitech keyboard! Buttons don't seem as responsive as my previous Logitech mouse, but it's not particularly noticeable (sometimes I have to press the button twice to clink on a link, but not too often). Less buttons than I thought, so less options when customising the mouse.
Summary: I like it. Cheap and cheerful. Works fine. My eldest daughter likes it but my youngest daughter, whose favourite colours are blue and yellow say it is "too blue". ..So you can't please everyone.
Summary: The LS1 1600 dpi laser mouse by Logitech is presented inside an extremely easy to open package with a manual instructions. The grip is very comfortable in both hands, the aspect is something between a laptop compact solution and a desktop one. I've tested on a Mac Book Pro (mid 2010) with Lion 10.7.5, it's completely "plug and play" and it shows a very simple control panel where you can adjust the sensitiveness and the buttons adaptation for left/right hand users.
Summary: A tad disappointed of the size being on the small size and the scroll wheel feels very stiff (compared to an older Logitech mouse I have). Laser tracking seems to work great and all surfaces except reflective ones.
