It is a great unit. I bought 2 of them. This 1 that I am rating is a great unit except for a couple minor items that add up to the 3 stars. The thermostat is off by 3 degrees. I have 2 other units that all cycle and maintain the same an this one is always off. And this unit makes a funny rattling sound when running. Like there is tape I side the unit that is rapping when it is on.. But as for the those 2 deficiencies the unit is a great machines. I wouldn't hesitate to buy more.
