I got the tank cover from Motorrad Stecki and it's decent, but for something that was in the realm of $250+ to my door I wasn't that impressed either. It does the job, but doesn't fit quite right had to cut the gas hole larger and now looks more oval then circle but otherwise could not open gas cap, the sides near the bottom really stick out and you have to find a way to stop the curling out so you don't break them while riding etc.
Could be better is my point, and way too pricey (it's paper thin).
I'm going to try the attack one and see how that is or go back to OEM which worked the best in terms of not being in the way when riding.
This is my experience only, just want to mention have heard from others the one they got (same brand) weas perfect so could just be the quality control and i got the not-so-good one.
