Easy to use, better mileage, more power, and a low price, what's not to like about this tuner!?

Easy as can be right out of the box. I even used a Mac and had no issues updating the device. Simply plug it into your vehicle after updating, pick your desired tune, let it do its thing, and done. Installing tune took less than 10 mins total. Capped off with the Diablo Sport OBDII cover. I plan to have a custom tune written by DiabLew once I'm done installing different exhaust components to maximize everything's potential.

I got this to add that little extra to my truck, running the premium tune (92octane) I can tell a quicker pick up on acceleration. Fuel miles you won't really tell a huge differance until you run it on the highway, there you can tell both increased HP when passing and better Econ in the higher speeds. Overall happy.
