Query: the handshake grip eliminates pain

I bought this mouse from Amazon a couple of months ago. It seems like a cheaply made thing for the price. That aside, the main thing is that after a week or so it completely cleared up the chronic pain that I have had for years with my right hand and associated pain spots on the arm and shoulder. I am so grateful for that.At first I had trouble with squeezing the mouse too hard. This problem seemed to have let up by itself and now it is all smooth sailing! I would highly recommend purchasing it if you are suffering from repetitive injury syndrome. I listened to all the reviewers who wrote in when I was figuring out which mouse to buy for relief.I am grateful to everyone who wrote in so that I knew what to get!
