Had mine done, maybe 3 years ago, the mirror sheets aren't the best fitting but the bumper is unmarked. To take it off I have been told, just make sure it's warm. It doesn't need to be taken off
1 thing, the cut out round the front badge isn't great either, they should have a complete piece and then place the badge over it.
Your price seems cheap, I'm sure things have moved on since I fitted mine.
I think it is good stuff !
