Particularly positive, I find that the manufacturer three complete sets of numbers and letters (to f) attaches that can be easily adhered to the illuminated area. The material is high quality, so you can stick the numbers without having previously glued on themselves or the application will wavy and form bubbles. Although there is only a detail, but I find very pleasant - who has been trying times, numbers of thin film to install somewhere, knows what I mean. ;) Although I do not have long-term experience, but I would imagine that the material does not fade even over several years.
Also a great detail - and it can not give enough stars you - is the enclosed 1: 1 template. A simple sheet of paper but immensely facilitates mounting. This is followed, all manufacturers of things that can be placed on walls and ceilings, even take an example! So it is likely to take the mask, it is addressed with the spirit level briefly, and then the three screws are rotated directly by the marks (or the drill, as appropriate). Leaf from, number and that's it!
Speaking of number off: by the Einhängemechanik the device must also not screw or the like - simply attach, push down, that's it.
Another praise there is for the use of commercially available AA-size batteries. The three cells can be easily and inexpensively replaced if they do eventually limp. The battery compartment is protected by a sturdy cover, you simply just have to postpone.
The luminous area is beautifully illuminated uniformly and is easy to read, so fully meets its purpose.
A thoroughly enjoyable product that I would buy again at any time and can thoroughly recommend.
