I decided on the basis of good experience with this set to buy a second. The first set was dedicated service to the Bosch PKS 55A (ie with use of clamping rings) made dignified and should be replaced by a new one. I had the first set (2011) did not expect much since the price is not a promise of quality in Verhätnis to original sheets.
I was pleasantly surprised about durability, running distance and average cleanliness and very satisfied.
Unfortunately, I was now (2013) very disappointed. The Reduzieringe (3 sizes for 3 saws) ie 3 rings for three leaves fall before the first use almost through the hole. A cone / a wedge shape I can not determine, unlike the first set. Even if initially as the visually promises fixation at a Baltt, the sheet remains after a few cuts are and the axis (saw) continues to rotate. For it to be hot and the blade (now overheated at the bore) absolutely useless even for the other two rings. Too bad!
Either the manufacturer has no quality control or the material is easy to increase even more affordable to the profit margin. Now it is probably still another mark sheet ....
