Before buying you should necessarily even think about what you so on inbox has (large / thick A4 broadcasts?), Because the BK is small (note mass!). but for whom this size is sufficient, which should buy, because the BK is very stable, the locking mechanism works smoothly and the installation is very easy. A star deduction because no suitable Pappeschildchen was there and the name badge securely holds only with a piece of adhesive. Tip: Transparent gluing tape use as Normal looks ugly after a while.
