Just an update. The staff sold it to a another customer despite originally holding a reservation.
All you needed to do was to post the link I posted in your original post, IMO
I read the very review before purchasing my projector and rainbows are mentioned as an issue for some people. So like myself who does see the rainbows on fast moving scenes it would be a reason for returning. So going back to my unhelpful comment a returned item may be a faulty / refurbished unit, a shop demo, or a customer return due to unacceptable visual effects. Is that more helpful ?
It's just 12m warranty, as expected... One problem I have with this unit is the noise level. Too loud even for this price. On the eco mode with dynamic black switched off its almost the same as in full mode only slightly lower pitched noise. I'm starting to think I've got a faulty projector... (annoyed)
I thought that, although the one I've reserved is apparently all new with all stickers and packaging intact. Will check if they offer extended warranty, but it is still being sold as an open box clearance item.
