The article itself, everything is already said in other reviews. Also I am very happy with it, especially since an electrical outlet is equal in reach behind the cot and thus the box is well secured.
However, one should look even if you buy the here quite expensive fuses. I've ordered through Amazon and the shipping was as usual very fast, but on the same day I saw identical backups for about 3.50 EUR in OBI and naturally annoyed me a bit.
