Quality construction. It does the job with precision. I had trouble understanding the menu (German).

Easy to use, I didn't even need to read the instructions. It works smoothly and without any problems in a semi-outdoor space (protected outdoors). The plastic parts seem to be of very good quality, I believe it will last for years.

Reliable exam preparation with many program options. It requires some attention to understand the instructions because there are many choices. I think it is a very good choice for external use.

Very good branded timer, easy to use and with many programs! I bought it on 20/09/2021 and after about 1-2 months, the screen stopped turning on. The backup battery inside, which is used to store the time and programs, had died, so the timer didn't work at all, even when I plugged it in. Nevertheless, I contacted the Brennenstuhl dealership in Greece and they replaced it immediately with a new one! Unfortunately, all batteries eventually die, and in this specific timer, you can't simply replace it like in a regular device. It is a 1.2V 40mAh Ni-MH battery that is "glued" onto the timer's circuit board. However, until now, as I write this comment, 1 year later, it works perfectly!

One of the best timers on the market!
It is easily adjustable, has a memory that retains the times you set in case of power outage, and the best thing about it is that it can be used outdoors!
