What I did not quite like is the fact that the terminal screws on the "L" to be somewhat delicate; Here, then, the difference from Busch-Jäger makes etc. noticeable. With a little caution is also to act as well. If necessary, one takes to mount the Same expediently the plastic set out (for installation use do not forget!).
Negative - The operating / installation instructions are in English only, therefore the hobbyist when he understands no English, the safe handling and assembly (probably) impossible. Here a German manual would be desirable. For myself, however, this was not a problem because I'm a., Familiar with the matter and of English (more or less) powerful.
Positive - the price and the fact that the dimmer is absolutely silent; it can be heard no noise.
Overall, for me an inexpensive alternative to partly twice as expensive products. The dimmer can I recommend, because it is suitable for LED yes and would buy it again, because it is unbeatable with the current price in the LED dimming range.
