Does anyone have experience with Blum jigs, specifically the universal template jig? I have a kitchen project coming up, and the installation of hardware has thrown me for a loop on previous smaller builds. I like Blum's hardware a lot and have zero complaints, but the installation instructions for many of their products leave me wondering if some authority should be on their way to strip me of all my degrees and send me back to grade school. Im not a cabinet maker or pro, but if this makes mounting and installing all Blum hardware effortless and perfect then it seems like it would be worth the $250 I would spend on a used set. Anyone have experience with this or similar commercial jigs?
