FEBI BLISTEIN

Hi, I am just looking for some replacement parts for my a4 tdi. I don't normally use the cheapest option available when it comes to parts, as I sometimes have discovered if you buy cheap you may have to buy twice!
I have come across the brand FEBI BLISTEIN whilst having a look and just wondering what quality is like? Is it a trusted brand that isn't going to need another part because of a cheap part failure?
Any reviews of any of there kit that people have bought would be appreciated, thanks

Timing chain and tensioner kit. It's a pretty important part so might juts go to main dealer but just didn't want to get stung of them really.
