Great buy on a a/c underpass unit
Came quick undamaged a/c unit looks good for price. Haven't installed yet in my 65 chevy short wide...

It’s alright
If you’re in a pinch or just cheap this thing actually works pretty good I’d probably buy it again

Fit my truck
Very well built, fit in my truck's cab to replace the factory unit. Installation was simple and straight forward.

Solid unit
Unit worked as advertised. It blows hard enough to cool my 54 truck down but might take it a bit to cool down larger vehicles. Would be cool if the temp switch has indicators for cold/hot etc but it’s easy to figure out by turning.

Air-conditioned for car
Didn't realize it had to be hooked up to compresser...didn't have one...can't use.
