Probably the best addition to the our backyard! I was considering giving it 4 stars because the app can be a little spotty and the whole spa water treatment is a learning curve and not so straightforward to understand. I wish they could offer more guidance as to what can or cannot be used with inflatable hot tubs, so you’ll have to do a lot of homework on that - but the product is great! The tub is so Sturdy and anyone can sit on the edge. The material and parts look very durable. For the price, this is an amazing buy!
