This a game changer for our little friends, having the day and night temps is so handy, and with the built in light timer, it saves having lots of extra boxes, the only slight niggle is the under/over temp alarm, there is no way to silence it once you know, and with the difference only being 5 degrees, when it swaps from night to day temp and vice versa, the alarm goes off for a good 10 min while it sets the temp, it also happens when we mist twice a day too
