I went through two of these units. The first one was completely missing the box of accessories. The second had major physical damage to the frame of the unit. The damage was beneath the styrofoam packing, and had to occur before the unit was packaged.

The unit does work well and the app is nice. There are some annoying vibrations that I had to figure out how to eliminate. Also, It is very easy to damage window trim while installing this unit. Please be careful.
