Great addition to our Phoenix backyard for winter when its too cool to use the unheated pool. Compact but sturdy and big enough for 4 at a squeeze, it heats well and hasn't noticeably added to our electric bill. Loved the plug and play ease. I thought it came with the steps included but it didn't and I had to order those separately - but it still worked out cheaper from Wayfair than any of the many other suppliers I looked at especially as the lockable cover was included. When it was unplugged and not in use for several weeks and the electric cable was left on the ground, water seeped into the plug and it shorted out when we next used it, so we had to replace the plug - so keep it dry! One star taken off just because it wasn't clear that you DO NEED to have a totally dedicated breaker  and outlet for it, which added to the cost of installation.
