A total of Dübler what it promises stops. My first work is pretty well done. Not perfect, but since I've never even dowelled - gone mad!
The guide could be improved though: The hint that not tighten screws, made me do it, the pins not quite durchzustecken and as long as the holes were still brand new, it has also fitted, but unfortunately succumbed and I've noticed only 2 holes later ( yes, you can patch up! I've got together and thus no real damage.
The drilling instructions may be printed larger - I think it's a great idea to put the holes on the workpiece, but a basic specification would be good and: you can see it almost not at mini-pictures. (Yes, you can already imagine why, but still)
And zuguter last: For shipping's negative points. I am in Ö home and it's not funny to wait a whole day to DHL. (Alternative: 2 hours Wegaufwand for self-collection). ö Post would much rather have been (as I can get from the nearby post office) and certainly have been at the expense indoors.
