I have been using the RAT 7 since Christmas. No problem with skipping totally smooth. I agree that the mode button is difficult to press but I don't use it much. I really llike the sniper button, it could be a little softer but this is no big deal to me. I have the horizontal scroll programed on the aluminum thumb wheel in profile 1. In the other profiles I use it for other functions. Overall I really like this mouse. I downloaded a Win7 KB command cheat sheet to help with the programing of the buttons.
