As with most if not all indoor projectors, you really have to be aware and carefull about the operating enviornment. This one claims to have a min operating temp of 40 degrees. Even here is NC, that can sometimes be an issue. I do like the auto-on feature which should take care of the power up issues mentioned. While 3000 lumins is not bad, it may still wash out in a otherwise bright display so when used, I would either have it in a darker area or dim the display when it is doing its thing.
