I have the Bonamici. Cost way less than any other non-Chinese (400,- euros). I have no negatives to report on. Peg is grippy, adjustability just right for me and seems robust. Crash test is not on agenda.
Bonamici's are fine. They are distributed here in the U.S. by Moto D. Scott is stocking spares so if you have a mishap you can find parts. They are made in Italy and the quality is top-notch for the price. I sell both Woodcraft and Bonamici and think they are about the same "build-wise." You won't go wrong with either. Just my .02 cents
Bonamici were not available when I bought my Dp rearsets, otherwise I would have purchased them. Although I do like my Dp set, the Bonamici appear to be a great option.
