First the positive: The timer is nice and compact, is powered by a button cell and has a sufficiently loud beep.
Unfortunately, he is not as high as the product images suggest. The housing is made of plastic cheapest (in the photos it looks like when the case a "soft coating" would have). The timer "wobble" when you press the keys: The magnet on the back is too far out and is attached to the wrong place. In the long run it just annoying, wennder timer constantly tilts under your finger or you have to settle it, to program it. However, the Benutzerunfreundlichste about this product is the operating concept: It takes forever until you set the time you want. The Konkuttenzprodukte of TFA are much more user-friendly here.
After less than a year, the timer ceases to function: it loses the time and the digits disappear when you hold it in your hands or something around pressed against him (the housing mind you, not the keys!). Probably innendrin anything corroded. Anyway, something must not happen after such a short time and only shows that the product has an incredibly poor quality.
I complained and the timer now bought with a new TFA, here is the link:
The TFA-timer is indeed considerably larger (with eienr AAA battery), but easier to program and has an overall significantly higher quality impression. With TFA I had had good experiences in the past. Expensive it is not (under 10), more available for 2-3 with black aluminum front.
I can only advise of the Westmark timer, he is indeed schän small, but brings nothing but trouble with it. The timer of TFA (see link), however you can not go wrong.
