I purchased the MAAC500 specifically for the time projection feature which my Wife needed for night observation. It has worked well, however, the digital display which I have on a bedroom wall has become a slight problem. The digits, which when all lit show 8's. When you are reading the time, the contrast between the lit digits and the unlit digits that give the time is not enough to distinguish what time it is. It takes a concerted effort to figure out the time. I'm not sure if it was this way on day one or it has deteriorated in two months. Otherwise it works fine.
