Pros: Used mostly for presentations and occasionally to display videos, amazingly visible in a well illuminated room, minimal difference between ECO and normal mode so you can go ECO mode in any condition, cool feature to adjust light output to compensate wall paint color (so you can convert any wall into a real screen), 6000 hours lamp in ECO, low noise, very good scaling of non native resolutions tried 1280 X 800, 1366 X 768 and 1650 X 1080, I fed a 720p HD OTA TV signal of a soccer game and the picture was excellent, actually amazing for a projector in this price range, brilliant colors, lamp replacement around 120 USD, small footprint for a 2700 lumen device, very good option for a data projector at this price. Actually this is the second Acer projector I bought for my group, very satisfied with the performance.
Cons: * No audio.
* No buttons, the remote control slides in the projector housing to be used as the button station, so if you lose the remote you will suffer, so better keep the remote attached to the projector.
* Only 1 year of warranty, all other Acer projectors have 2, not sure why, however for less than 40 you can add 1 year of warranty.
* (Not a con, more like a suggestion) Seems like the auto keystone correction is too sensitive and may try to readjust the image every 5 minutes or so, that causes image flickering, so manual keystone adjustment is the way to go.
Other Thoughts: Acer is doing very good electronics at affordable prices, I have an Acer AMD laptop (4 years old now) almost indestructible and very reliable, 2 23" LCD monitors bought for less than 139 each, very satisfied with Acer, Keep the good work.
