The only issue I had was just this week removing it from my Saturn to install in my truck. The RJ45 plug was jammed, and unknowingly I pulled the whole plastic retainer out of the back of the
scangauge. I bent one of the leads, but managed to straighten it and snap the retainer back into the back of the
scangauge.
I guess if you are removing it often from your vehicle it could be something to watch out for.
Other than that it has been good.
