Pleasantly surprised with this hot tub. It was a birthday gift for my husband to see how much we would use one. It's what I call a plug-and-play hot tub. You don't need a bigger electrical outlet. It will take longer to warm up and does cool down faster, but that hasn't been a problem for us at all.  It's usually the two of us or us and our daughter, but we've had 4 and been very comfortable. 5 is pushing it a little. The gray color is nice and won't weather. We have been so happy and don't feel we need to buy a more expensive one because this one is great at about 1/2 the price of others we had been looking at.
