The previous review I can connect sometimes, but

with me the IQ has been sufficient for labeling, though not without difficulty. One little window opens inwards, the other - to the outside. :)
The mailbox can be pulled out, the depth was enough for my wall 25 cm + 3 + 3 = 31 cm.
The safety screws (the "bits" as Torx but with a hole in the center for example "TR Torx Bit Set - 10 bits - Torx with 5 corners - 5-Star" you need, that's right.
One point deduction there is really only for the price: the thing looks chic, but nearly 300 EUR is not worth certainly.
