This air conditioner was light weight and relatively easy to install.  The accordion wings on each side look cheap and not durable enough to withstand removal and installation of the air conditioner each season.  Functionally, it has three fan speeds which is nice.  The louvers fail to redirect the air left and right and there is no up/down adjustment which should be standard.  When the louvers are set far left, air still comes out to the front and right.  Just a poor design.
