This was a decent project to put together but not horrible by any means. I did it by myself in a about 2.5 hrs (5'6" female), but I like things like this and used a power tool so I wasn't sitting there twisting for hours. Just be sure to back off and not over torque. Made sure I was strategic about laying the large pieces out so that when I lifted, it was already basically where I wanted it to be as there was no way I'd be able to lift on my own once completed. The only downsides are the blower is a bit louder than I'd like when heating, can live with that, but now after using it fairly regularly, even just the light feature with no heat has a rhythmic rattling that is getting pretty annoying. Need to see if anything on the backside needs tightened.
