putting together was pretty much straight forward, they quite solid and are doing the job they meant to do, already out every weekend gigging with no problems, cant wait until I change the skins, which I guess is the only negative feature which in itself is not a negative, ie: there is always room for improvement, just like any other drum you seek the best skins. As they are, they sound is tight as it is, I must say this is one of the best buys I have made for a long time as regards to additions to my kit, would recommend these to anyone who is seeking rota toms as the price just makes these a perfect choice!
