Very good material ... hoping that the rest on the long term.

After going through the Acer and Optoma brand, I finally passed by purchasing the Benq W700, very close relative of W750. Unfortunately, after 2 years of loyal service he suddenly passed away in full projection (burning smell, you can not restart. The lamp was only 1200 hours.)

Despite this incident, I decided to replace it with the W750 almost identical to recover the assets that had seduced me: Commissioning simplicity, image quality, wealth of connections and settings.

I just have 2 sources of disappointment:

- The optics cover snaps directly on the development of wheel, causing it to move and forced to readjust to the next viewing. The optical cache W700 is smarter and more practical (it remains completely fixed because clipped on the camera body)

- Much noisier than the W700 despite what may indicate the technical specifications of these two models. My W700 was not only quieter during projection but he had the advantage of being extinguished in less than 5 seconds. The W750's fans continue to run tens of seconds before dying: I gather that much warmer.

In the end I do not regret buying this product but I will not hide my concern about its longevity in light of my previous experience.
