It's a good deal if you have a proper room to put it in. The big reason that these are selling for so cheap is that at $2,000+ they make almost no sense when the 100" TVs are now competitively priced. A TV is brighter, and is native 4K resolution. You may also find HDMI 2.1 inputs with proper 120hz support for gaming as well.
So, while I am a huge fan of front projection, Hisense locking in these projectors to only 100" diagonal image sizes is a tough sell these days. It's not a bad deal if you only have 100" to work with in your room, but in a lit room, I'd go for a TV every day of the week.
