Very well built and easy to mount. Plenty of cooling, very quiet, 3- 120V 15A outlets plus a hard-wire option, heavy duty output terminals with 5/16" stud and nut using 13mm or 1/2" wrench allow for wide range of connecting the 2/0 cable to that I got from Fast%26Quiet available in 3" increment lengths for a perfect fit. 6000W surge allows my air conditioner to start with ease. even though the mounting holes didn't line up with the studs, you'll see in the picture how I sandwiched it between two boards with a bevel across the studs which even allows for some back and forth adjustment while wrestling those fat cables into position. Trusted brand even if it's made in China. I would buy it again.
