300 bucks for a window unit?? That’s basically free compared to what my landlord charges in repairs.
So they dropped it 20% but only for Prime members… is that like a scam price or what? I thought Prime Day was over already lol.
Wait I’m confused, it says 10,000 BTU and 450 sq ft. My apartment is like 600 so wouldn’t that mean it’ll still overheat?? Also 54 dBA sounds loud like a fan constantly.
Prime membership like $15 a month? That math doesn’t even work for me. But also if it’s the first time it ever dropped price, then maybe it’s not good and they’re dumping it. I swear these window AC reviews are always hit or miss.
