The supporting frame is stable and multi-adjustable in size (length and width). However, the adjustment with screws and nuts is quite time-consuming, so that a rapid change between two different big players is not possible. But its own drum should for the cheap price anyway be in it for every player! From the sound I am very pleasantly surprised! Of course, one must only times the skins vote right (leave or vote by an experienced drummer, drum key was with me with this) set, the integrated damper to the desired damping and possibly readjust the snare carpet. Then the instrument sounds but really good. Of course one must not expect the sound of a three to five times as expensive 14 inch brand snare. Unlike some other "cheap-China-drums" but also the skins are useful. 12 inches is about 5 cm smaller in diameter than a "normal" snare drum with 14 inches. In my opinion, making it ideal for the young in all marching bands and other marching groups. I use the same snare with good experience as Caixa-replacement in a school samba group (with slightly stiffer taut skins).
