However, both devices are useless. The keys do not react. Taking the batteries out and put them back on, you can use the device for a short time until the buttons are not working.
But even then, the time is measured nich properly or the device has Aussetzter what makes this timer just useless.
Since I bought the same equipment and 2 both have the same defect, it seems, unfortunately, to be a coincidence.
Only can dissuade from each purchase.
