Love the concept of this projection clock/outside temperature. however, every couple months or so it decides to readjust the time 4 hours??? I have it set up correctly and for months it will go along nicely. Then randomly it jumps the hours just to f@*& with me. I'll wake up at 2AM and it's telling me it's 6AM, not funny! This has happened twice in approximately 4 months. The unit is pretty cheap and flimsy, you get what you pay for. But if this is your primary alarm clock, don't trust it! Still, I do like seeing the outside temp on my ceiling and as far as I can tell, it's fairly accurate.
