Where to buy
I don’t reprint Amazon’s price here — Amazon shows you the live one, which means the number you see is always current rather than whatever I last wrote down.

My verdict
I check prices, not products — this confirms the number is real, not whether brightness or focus performance hold up for home theater use. And it holds up: this is substantially below its real recent average, not a stale list price. Worth knowing upfront: this listing's price has moved around a fair amount over the past few months, including a brief dip earlier this summer that may have matched or undercut today's price — so I'm treating this as a strong, verified price rather than claiming it's an outright record. This is a genuine 4K UHD compact projector, not a lower-resolution unit marked up to look premium. The tradeoff: compact projectors like this generally trade some brightness and throw-distance flexibility for portability compared to larger home theater units, so factor your room setup into whether this fits.
Buy it if
- Buyers who want a genuine compact 4K UHD projector for home entertainment at a real discount
- Anyone setting up a portable or small-space home theater rather than a dedicated large-throw setup
- Buyers comfortable with a verified strong price rather than an unqualified record-low claim
Skip it if
- You need maximum brightness for a large or well-lit room — compact projectors trade some brightness for portability
- You want the absolute lowest price ever recorded — this listing's price has fluctuated enough recently that I'm not confident this is the outright floor
- You need a long-throw, dedicated home theater projector — this is built for compact, flexible setups
