My puppy loves it! It is not to big for him to pick up and toss around. It scared him the first time it squeaked. The only problem is my other dogs like it too, so I will have to order a cople more!
positive

Just opened my plastic package because hard to see if center pin was copper as pictured in ad.. sadly it was not. By the way, do not tear open your package because it states on the package,"No returns if bag is open" what a waste, I should have just driven to an autoparts store.
negative

Don't waste your money to buy this, the mouse can't leave the mouse pad for 10 seconds, otherwise it will automatically power off, and my mouse pad rgb broken within three months.
