I was struggling to keep my water clear and my cover free of stains. I tried all sorts of chemicals and combinations and cleaned my cover weekly, no luck. Ever since I put this cover on, my water is crystal clear and my cover has stayed clear of stains and my filter is easily 50% cleaner, probably more and easier to rinse and clean. It requires some tricky cutting, especially if you do not have a square tub, and when pouring chemicals it can be awkward to remove but it is so worth it.

It was easy to cut and fits my tub well

The bubbles lost their air after 2 years. Without bubbles it doesn't insulate as well and more water pools on top of it. For my second one, I trimmed it smaller than the water surface, not following the recommendation to make it larger. When smaller the water will pool less on top. Water evaporation cools the spa so you want the top as dry as possible. The small amount of exposed water around the edge (at most an inch) does not cool much since it is a very small fraction of the water surface.

I use this cover in my 280 gallon hot tub in Iowa. It was plenty big and was easy to trim with regular scissors. I saw an immediate drop in energy consumption during winter. I don't plan to use it in the warm months. My chlorine use is less also.

The liner has increased the thermal efficiency my hot tub. Allowing the heater to warm the water faster.

So convenient and very quick arriving.

The cover keeps the spa warmer in winter and I can raise the temperature by a few degrees in direct sun without running my heater.

i bought a new hot tub cover. it came when promised, fit well, looks great. the price was reasonable as well. I would order from spadepot again in the future.

We bought this to replace our hot tub foam inner cover. We don't know how long this will last and hold up to the chemicals like the foam one did. It's hard to give a review about something that we haven't long enough to determine it's durability. With that in mind, it is so far, so good. It is keeping the heat in the hot tub and not allowing heat loss which was the purpose for the purchase. We will see it's longevity

Excellent quality . Exactly as ordered
