I ordered the projector at Warehousdeals, so the second platform of Amazon. The article described a condition as "very good" and should only light scratches af have the surface. After the projector has been delivered on time, I have connected to my PS 3 it immediately via HDMI and unfortunately had to find that massive pixel errors were present in the upper left of the screen. Furthermore proceeded over the entire width of the screen a black line 2m. The picture or video projector were thus completely unusable and why only 1 star. I can not understand why Amazon has the "very good" offered by a state. The lamp time was approximately 520 hours, so I am assuming that the owner has returned the projector within the manufacturer's warranty on Amazon. Unfortunately, the problem seems to occur more often because it has been reported in various forums that 600+ pixel error after 500 the BenQ W - originated 600 hours. I do not know whether the DLP chip Dark 3 such. As the Acer 5360 Bd is installed, because the errors are likely to be due to a defective chip. At least Acer is 5 years warranty on the chip! So I would advise against BenQ, as at least fairly quickly arise pixel errors. For me, this looked white and spread across about 15 - 20% of area. At least Amazon withdrew the projector without hesitation and I have, this time again, the Acer and BenQ 5360bd W 703d ordered as a comparison.
