"It's exceptionally cheap, but its cooling power and noise claims border on fiction."
The 8,000 BTU (ASHRAE) rating is an older, less realistic metric; the government-mandated 5,000 BTU (SACC) spec means this unit has the actual cooling power for a small bedroom or home office, not a 350 sq. ft. living area.
This is for someone on an absolute minimum budget needing last-resort cooling for a single, small room. If the choice is between this and heatstroke, and it's the only unit you can afford, its low price is its primary virtue.
Anyone sensitive to noise, concerned about electricity bills, or needing to cool a room larger than about 200 sq. ft. should look elsewhere. A slightly more expensive unit from a known brand will likely be quieter, more efficient, and last longer.
