Summary: this unit is small and easily installed. i put mine thru a wall in a small shop(@120sq.ft.)for the money it's a good deal. haier brand is carried at stores like walmart and lowes. that make me more comfortable with the purchase with thier name behind their products. it has a digital display and comes with a remote. it runs on a regular outlet, not a 220volt plug. the only downside is that manufacturers of units this small usually over estimate it's cooling capacity.
