Personal Experience
In 2009 our company purchased 5 of the EP1691 projectors to use in our seminars. We tavel the country and the reviews for this unit were good.

Problems
Since that time, 3 of the projectors have major overheat malfunctions. Two of the three projectors would shut down after the first 15 minutes of use. The third would not illuminate at all. The fault lights indicate that the lamp is overheated. All three had new lamps installed and the filters were cleaned but this did not resolve the problem. The cost to have them repaired is as much as a replacement.
