Seriously - don't buy it.

I wish I'd read the other one-star reviews. They are absolutely correct. This whole setup, bell, transformer and bell push is utterly shoddy.
The bell itself doesn't ring properly and is sensitive to gravity. In some orientations it hasn't enough strength for the striker to hit the bell against it's own weight. The terminal screws are tiny self-tappers directly into soft plastic, requiring the utmost care to tighten and barely holding the wires.
The supplied transformer came with one terminal screw-block thread stripped (I should send it back but instead shimmed the thread with a piece of brass in my workshop). It's designed for rail mounting without any cable clamping and is quite frankly dangerous for DIY use.
The bell push is the worst part. The body protrudes out of the back so you have to drill a large recess for it in the door! A small incandescent bulb is supplied. I should estimate it's life in days, maybe a week or two.
