I got mine from bhp motorsport 2.5 years ago
Nothin special only good thing is you never need to buy another one so saves on service costs if you keep the car long enough
They good and easy to use
You can get custom cal files from them you just have to but it separate
I gave had mine for 2 years with no problems and is usefull for clearing fault codes etc
It's so much more than a remap
