Optoma UHD51ALV True 4K UHD Smart Projector w/ HDR (Open Box)

Let me start with projector itself. Very decent projector, bright, sharp , nice colors. I am not going to go to details as I knew exactly what I ordered based on research and reviews. Product as it is is not bad. There are better projectors outthere for much more money and worst ones as well.Let me go to actual renewed-refurbished unit.1.It came in plain box as noted in description, and right after i unpacked it something was rattling inside. I kept on turning it around and it kept on bouncing around. As IT technician myself i decided to open the cover and assess whether it was broken during the shipping or screw got loose. (That would decide whether to ship it back or keep it, especially when everything takes forever to ship because of COVID.) - It was screw that got loose from motherboard protective panel. I fixed it. Motherboard protective cover is smashed - looks like someone stabbed it with screwdriver to get it in place. Terrible job.2. Unit has missing lamp filter.3. Battery cover on the Remote control has broken tab, so cover would not stay on.4. Wireless USB Adapter for Alexa is MISSING. Not in the packaging with all the Cables. Just forgot to includeI would like to meet technician who refurbishes and renews these machines, because it is such a sloppy job I simply just can't believe. Definitely not worth money i paid for it....
