This host (casing) is rather common for 1W 445nm lasers, or for 400mW greens. O-like (they are from Singapore IIRC) had it for example, and they currently have something rather similar.
But who made the laser and how good it is .. it's not so simple with those Asian products. You can have one good company with good laser .. and another laser JUST like it from different company, which would be rubbish.
I haven't heard about laserdance. It's basically impossible to tell who made the laser. We could judge more if we saw the insides, but don't dismantle it just for looking. If it works, it works.
