The structure designed is a little difficult due to the lack of lens shift and also it is not easy to find an affordable universal mount, as the hole spacing is already very large, but this does not lead to devaluation of the projector, because these are just personal opinions and was already known before buying.
The picture in 2D and 3D mode is very good for this price and so what I've seen you get for that price is hardly a better 3D video projectors.
The bundled 3D glasses are very light and comfortable to wear, even for long periods. Charged via USB it is what lasts about 30 minutes. And after that it is ready for several movies.
My previous Beamer was a Panasonic PT-AE2000 and I have to change previously not bereuht.
