Designed for seniors:
"I can't tell you what this mouse has done for me. I am a 74 year old woman with a hand tremor. I play a great deal of online scrabble which involves a lot of dragging and dropping. It was torture to try to place letters with a conventional mouse. The harder I tried the more my hand shook. A friend led me to a website where I ordered your mouse. It is a Godsend.
I am all over the board with letters dropping them precisely where I want them to go. Your easy to use mouse is disigned so well for not only people with tremors but for all seniors. I am inclined to buy another should this one wear out. Thank you for beating my hand tremor. I will look for a website for people with tremors so I can recommend your product. Thank you for all your help."
