Love love love this Aquarest! We had to purchase a plug and play because of our old electricity in our old house. We almost bought a used hot tub for a little more and I am so glad we did not.Its been up and running for 6 months. The shell construction is amazing and sturdy. The surface feels a little scratchy at first but will go away after you clean it a couple times. For the initial fill, I wiped it down with hospital grade alcohol then rinsed, we should have done it twice because there was factory residue. I change the water every 3 months because of heavy use. The waterfall is not very exciting but the lights are beautiful(dark blue is my favorite). The jets are more powerful than I expected but keep in mind it’s a plug and play and not a 10,000 hot tub. If your on the fence ,get it! We have 2 adult children and we are not small people, it fits us all comfortably! It makes for wonderful family time because they can’t bring in their phones!
