I bought this ankle shaker to use alongside djembe, but I found this more useful as a percussive instrument for recordings (by recording separately). As well I tried to experiment and use it on cymbals as a sort of demfer/shaker stuff, and it sounded pretty good as well.
sadly original product looks bit different than in a picture provided in the description, but it is still usable and awesome sounding piece of gear for drummer or percussionist.
the durability of this shaker is not really impressive, but it depends on how you will use it. The connections of pieces are not perfect, but it is easily repaired so there is no big problem because of it.
