Yeah, I also got surprised paid around $250, and it just stopped working one day. emailed them, they said they can send me a new one, but I gotta send the old one back, and I use my warranty. I did what they said and this one works fine, but im not sure if I wanna plug it back into the X5 because now I don't have a warranty. not even sure if the X5 is the cause.

But yeah, I'll see what happens. I wanna check the live data to see what's going on.
