Only slightly better than the 16 year old parts they replaced. Just buy Mercedes- Bens parts.
I needed to replace my boot openers as they were getting weak.
I bought this thinking that more expencive German option would be better than a cheaper pair. But this is not a pair it is £10 more than a pair, for ONE (my mistake).
So I bought another one, now I have a PAIR for £35 more than cheaper options - £16 for a pair.
However, they are NOT A PAIR as my mecanic found out, each side of the car is diferent. Not the same as mentioned in the advert. Fitting = Both sides.
Now they are fitted the opening is better, but not much better, not £52 plus fitting better. On a hot day, 25C, they open very well.
On a cold day they are SLIGHTLY better than the 16 year old original parts. The boot does not always open fully.
I should have bought Mercedes-Benz parts.
