I first bought two, and I was actually hoping that the sound match exactly, but as there was little difference, I decided to get 2 more, looking for good luck and get it even more similar. I discovered that this slightly difference is giving more range of sound to my beats, though. It is finely made, even that is plastic, the holes give a big range of sound, and it is well balanced. It can create a nice loopy sound (may be that's why of its name), which is easy to keep a sustain release and it is flowing easily, and giving a continuity to the beats. Good instrument, for bargains price!
