Quite expensive I have to say, for what it does, but it is really good quality.
First, the aspect is quite good. It looks strong and you are not scared of breaking it while using it. The sound is precise and quite good, of course mainly in low frequencies, but it is what we need with that. It reacts each time you touch it, so you don't need to kick it too heavily.
It is quite heavy and stable, so it won't move too much while you are using it (still, find a way to maintain it).
It is delivered in a protection package that is quite useful.
The best one I tried.
