This is a lightweight when empty spa that is easy to maneuver. If you chase the 120 volt model, when the instructions  say it make take 20 hours to get  hot , they aren't kidding. The first time I ran it the water about 70 degrees , 10 hours later it was 91 and it was around 40 degrees. The plastic shell is pretty smooth, however you can scratch your back a little. The cover is nice with clips you have to attach to the tub The motor is a little loud but nothing like a pool pump loud. It's kind of frustrating that you can't leave water in it during a freeze, at least not according to the directions.
