I like them very much...the only two negative things that I can say about them is 1) they are very fussy to set up perfectly as they are quite hard and flat (a good thing) so the toneholes must be very flat and the cup must be well-aligned and 2) they are reasonably noisy to play as they make an audible 'slap' that is sharper than the typical 'thud' of a pad...the audience doesn't seem to be able to hear it, though, even in a small club (even my wife in the front).
