Great little spa. It's comfortable, easy to use, reading the manual is not necessary, and we just plugged it in. It's definitely not as luxurious as the fiberglass spas; it is a sitting position spa, no lounging. The jets are nice and can be turned on by side (2 chairs on the left or the 2 on the right, or all on). It is easy to drain, and clean the filter. 6 people would be a tight fit, and 2 of the 4 would be sitting about 6 inches higher and have no jets... ok for a child, but adult, probably not. The spa also comes with a cover. It is sufficient. It covers the spa and keeps the heat in; however, it will blow off in a 20+ MPH wind, so we have a large brick on either side of ours.
