one little thing, it doesnt quite work like a regular turbo timer. you have to actually hold down the 2 buttons to iniatiate the timer then it runs from anywhere 1 to 10 minutes or whatever the settings are. it doesnt come on and time wen you pull they key out. not to say anything bad about this product i work at best buy and have installed a couple, and will be getting one for my z. just thought id let you all know.
