I needed one of these in a pinch while waiting on repairing or replacing my central A/C. It works ok for the price - but draining the water is more difficult than it should be with the drain hole at the bottom rear of the unit. (You’re supposed to drain into something below the unit but that’s not possible if you don’t have it by a basement floor drain or the like. You can put it up on a chair or table but it’s heavy and that’s cumbersome.
