Instructions in German, not even in English. The screen is small with small letters... I haven't been able to program it yet. Only time, WITH MY FRIEND'S VIDEO, I PROGRAMMED, BUT IT MAKES A BUZZING SOUND IN THE POWER... poor construction and dangerous

It has been 2.5 years since the purchase and it works perfectly. It still doesn't lose its program if you unplug it.

Very good for its price,
after about a month the screen stopped working, so I preferred to open it because the service process was time-consuming and I didn't have the receipt, but in the end it works fine

The mechanical timers are very easy to set up but they make a relative noise like an out-of-tune clock. The digital ones are completely silent. This particular one seems to be working, however, there is an issue with its programming. The instructions it contains are in English and German (where it is called GRUNDIG), but they are almost useless as you cannot easily understand the programming philosophy of the device. Search on YouTube for a video titled Crest Digital Timer Setup - Part 1 and Part 2, it is exactly the same machine and describes the steps precisely.

Instructions only in German, I managed to only set the time, I don't know how to start and stop it. Only for Germans, it doesn't have instructions in English either.
