I was looking for a kick drum mic on a budget and having read other reviews of this BD300, which I believe is Thomann's own brand offering, I wasn't expecting much at the price - however, I stuck it in the drummer's kick drum on a small stand and placed it about an inch away from the beater skin just opposite the beater.
It recorded well enough, but it was only when I was able to properly listen to the results in the context of a mix that I was very pleasantly surprised with the results.
Nice and crisp, full-weighted 'thump' with a little bit of click in it - perfect. Wasn't too anodyne and still sounded like a real kick drum, but more than good enough to place in a mix with a little bit of the bottom end rolled off.
More than pleased at this price - I would recommend the BD 300.
