Among the features:
Hochzaehlen 1) time
Runterzaehlen 2) Pre-set time and give signal
Selectable signals are light, vibrate or beep. The can be used individually on / off, without complicated key sequences using the slide switches on the rear panel. We see what is directly set and can change in yourself it quickly. The slide sit so that you do not accidentally.
Unlike most other timers that can count not only 100 minutes but whole 20 hours. A slide switch on the Ruecksaeite Selects the display between minutes and hours-minutes-seconds.
The device can be attached with a magnet on Metallflaechen but also clipped to clothing or placed on a flat surface.
The timer was produced in China and the build quality seems good.
There are 3 points that are a bit ugly:
1) Each time you press beeps, vibrates and lights up a long story short (depending on what you have everything turned on). This is completely absurd. It is sufficient if it actually does at the set time.
2) The magnet is slightly sharp-edged and not covered by a schuetzenden foam rubber. He verkrazt Possibly metal surfaces.
3) The batteries are after 6 - 12 months empty. Namely, Duracell, and even if the device is barely used. On closer inspection, the batteries are not completely empty, but because of the easily fallen battery voltage is the beep then just quietly, the red indicator blinks only weakly, so I have to replace the batteries. After all, there are normalle AAA batteries, nothing exotic.
Otherwise, a device with which it is fun to work. And at a good price.
