I had the Logitech G500 but it had a issue so I called Logitech and it was still under warranty BUT it is now discontinued and they sent me a G500s which is the replacement. They didn't even want me to send the old one back. Great customer service and I LOVE the mouse, If you like wireless the G602 looks nice and is a newer offering from them but have no hands on with it. My brother has a G700s and it's a good mouse with no lag as some wireless mice have had in the past. All the choices seem like good ones other than the Tt eSPORTS, Can't say I've ever even seen one or knew anyone who had one so I'd shy away until you hear some reports if there any good or not.
