Quite a good timer, relatively easy to set up and with plenty of programs to customize it to your liking! The only downside is that the locking mechanism on the rail is not very stable and doesn't lock well, resulting in it moving quite a bit without actually coming off its position.

We have had it for 2 months in the apartment building for the garden lights. However, it also needs a power relay to be 100% sure that it will hold (due to loads).

Very good. It has 16 options to turn the lights on and off. You can also use it to turn on and off two different lines. When it is on, it passes current through one output contact (No4), and when it is off, it passes current through the other output contact (No5). So you can have some lights turn on at certain hours and other lights turn on at different ones; hello. Think of it like a pedestrian traffic light (green-red). Overall, it is very easy to connect and adjust.
