Medium level skill to put together. The directions are kind of weird but once I read through it all once, instead of step by step, it was easier. Plus the English and Spanish directions were mixed in the booklet/manual so I had to flip back and forth.  Also, I had to create my own order of directions or else I would back track steps. Over all (I got two), they are clean cut and look nice. I wish I would have gotten one size larger. Not very good air flow for the area it’s in. Would be great in a small/teeny room.  Simple and efficient enough for the price. Make sure you measure your area really well before picking your blade size.
