The one thing, the ONLY thing to worry about is the switches. They're small and kind of fragile if you aren't careful with how you try to turn them on or off. (presuming you bother to find batteries for it and install them) Just about everything else on Quakewave is dead solid.

Open it! It's so nice and looks so good next to Soundwave. In fact, I think it even overshadows Soundwave a bit. Everything about it is Masterpiece quality, even official Masterpieces aren't at its level.
