Query: Beware of this "mouse"

I changed my wired USB Intellimouse Explorer with this one.Read this: If you are going to use this mouse for Web Development and/or Gaming, better buy another mouse, not wireless.* I had troubles to get it work because of syncronization* The wheel is not too soft... it it the harder wheel I have ever touched!* Side buttons are for X-treme Large Fingers (F**k), Why 5 buttons if you can't touch them?* THIS MOUSE IS *** HEAVY ***, come on we are on 21th Century!* After all of this, the price is really high because of being platinum. there are other wireless microsoft mouses half the price.The only pro of this mouse is the really new style and its ergonomy (Right handed only).
