PCMag reviewed the Hisense 8,000 BTU UltraSlim Smart Inverter Window Air Conditioner, listed at $339.99 as a Costco exclusive. In PCMag's testing, the split-housing design lowered a 360-square-foot room by 10 degrees in 22 minutes while keeping operational noise exceptionally low by keeping the compressor outside. The unit provides Matter compatibility across major smart platforms, detailed app-based power tracking, and an included mounting bracket, though buying requires Costco access.

## Media review

PCMag rated the Hisense UltraSlim 4.5, labeled it Outstanding, and gave it an Editors’ Choice award, citing its slim profile, quiet operation, cooling test, and smart-home features.
