Mine works perfect out of the box - I see others
have complained that there’s has not worked at all or the screen or projection was defective - mine has worked fine in all respects - screen has great brightness and can very in 4 brightness levels - the overhead projection is clean and crisp in Red Laser color , projects very well even on distant wall or high ceiling - sets itself to correct time via Colorado Time Signal , takes only 2-3 mins to self-set, also manually setable - unit is small and compact but seems well made - will even self-reset after power failure after a few minutes - i’m very happy with this clock and especially like the cieling projection feature - looks really cool . Overall great buy and I highly recommend.
