Pro:
30000 Led life with three years warranty. Light path should be fully enclosed, ie it is protected from dust.
Image is very natural, the fan noise barely audible.
On and off at short notice possible, no cooling down.
First LED projector that can compete with other lamp projector. Had an Epson 6000, although it had more contrast, but more unnatural colors.
Very good image parameters such as inter-frame calculation, noise filter, edge enhancement etc ..
USB Hard drive works very well
Contra
No 3D
Borderline case of bad lighting conditions
Spatial relations must fit, ie at 2.5 m diagonal, the projector must have approximately 3.5 m distance and be positioned approximately at the bottom of the image.
Overall, for me the first really good affordable LED projector that can compete well with better LCD and DLP lamp models. Full recommendation!
