I have worked on all my cars for over 40 years (replaced, shock absorbers, burned, timing chain, VANOS etc.). I was hesitant to buy it at first because the price seemed too cheap compared to similar manufacturers. BUT I have to say that not only were they packaged professionally and carefully, the build quality is immaculate and beautifully designed. I can tell the quality when I see them and they have been made to strict standards. Thanks!
