To say the same: This is incomprehensible for ABUS. On the one hand a great product with great quality and a guide that is not worth it to be so named. If not for the Internet and Youtube would it not nice people and companies would (not ABUS!) And produce an instruction video and into the net would (Thanks Locksmith Oldorf), the installation would have been well accompanied by vigorous cursing and more. So was the installation, thanks to the finesse shown there, fairly easy and quick to do. That, however, compensation components for the wall brackets are dimensioned so sparingly, is not exactly brilliant. And a possible replacement is so beat Beech as the spare parts service from ABUS has indicated? -People That is plastic pressing member! Are you crazy? About 4 Euro for a spacer? For? Nope, did not work !!! An illustrated guide or even a video production (but please with professionals and not nerds) would be a solution. And a service number for the spacers might also customer-friendly! So I can only give three stars. Quality, and when you know how it really goes, would actually 5 star. But there's two star deduction. Please, dear ABUS people; think and change!
