After an easy to carry out fine-tuning, the 2-level LED Spirit Level is a very good companion. Especially at night shots indispensable. The product name 3D is indeed physically incorrect because it does not display the vertical, which would be technically too complex, and also completely unnecessary. (Who wants to know how much he keeps his camera on the ground?) That does a 5 star rating but no demolition. A German manual would be for many users certainly makes sense, but my version was not bei.Das product per se is highly recommended.
