DO NOT BUY! The device is really really bad. The battery lasts just 4-5 hours when charging via USB label (12 hours on the charger). So exactly until the animals are active. The mini solar panel does not manage to charge the battery. The device stood in the sun all day (at 30°C, cloudless). When I wanted to switch it on in the evening, the LED was already flashing and informed me that the battery would soon be empty. Really, really useless - save your money!
ok so far with a short interruption
