The warranty is lousy though. I had to send it back twice for electrical repairs in the first year. It cost 35.00 for service each time and 16.00 each way for shipping, even though it is suppose to be under warranty. The tub works like a big bathtub bubbler, and while it loses heat while the air is blowing, it stays hot enough for a couple of cycles, and the water moves really well. Because it is inflatable, it is extremely comfortable, very portable, and easy to move and drain. It is also tough and durable and should last a long time. The filtration and power pack are cheap though, so the filter has be cleaned frequently (easy enough with a garden hose) but a hassle nonetheless. A Nature 2 water purifier really helped with the water quality, and the type A filters for Easyset pools sold at Walmart are nearly identical, fit fine, and are much cheaper than the ones sold specifically for this spa. All in all, I would say if price or portability are big factors in your buying decision, than it is probably worth it.
