I had a 16" floor tom, and with Pearl JG-16 Jungle Set Adapter I converted in a kick drum almost in one minute. The pieces are very sturdy, and after a few months of using it for gigging they haven't decline in quality. That's the good side of this pack.
A grey side, because, is not that bad, is that shut be include in the pack every thing you need to transform your tom into a kick drum. I could do fast because my tom was mount in a arm and has the attachment part, however, when I try to do with another tom, I could not do it, because it was missing that attachment part.
In general is a very good product, for a good price that let you transform your old drums in something new.
