The temperature station was delivered quickly (as always with Amazon) Commissioning went easy. Since now over 4 weeks there are no complaints / failures / repairs etc. So: Everything was great! So why only 4 stars - and not five? The batteries were not there! The clock is a quartz watch - but no clock. (So you have 2 times a year manually one hour before or Reset) But anyway: for under 18 a great device, very easy to read.
