Ok so here's my thoughts. I read so many others that rate it bad. Listen, this is not a jacuzzi cover. This is a sacrificial jacuzzi cover/cover to save your jacuzzi real cover that was a $900 investment covering your spa.
Ok so I'll explain my situation.
I live in Houston Texas, basically the middle of Hell. Our summers here are around 110. With your regular expensive spa cover in this heat it will only last a couple of years at the most. What this cover is for is to put over your regular expensive spa cover so the sun and weather beats down on it and not your expensive cover. These will then save you from buying the $900 cover every couple of years.
This cover is your sacrificial cover, it saves your thick expensive cover, this cover will last a couple years in this heat, then toss it and buy another one. And your good to stay good as good as new for a very long time.
In the mean time you paid around $40 every couple of years but you saved $900.
Ok, my rating on this cover: is its pretty good, yes water does sweat thru but my other cover Sheds it off and keeps looking like new. I'll be glad to get a couple of years out of it, I'm thinking probably 3yrs. I like it, fits great. It has 1 motorcycle helmet type pull strap and 2 pull tight draw strings with hold tight holders on them. Good material. It's a good buy.

I purchased this tub cover to protect the top nearly 1 yr ago and it's still going strong. Hot tub covers are expensive to replace so this additional cover is well worth the investment. It fits my tub perfectly and secures snuggly with strong velcro down one side and a strap around the base to secure the bottom. It stays in place! Not only does it protect the cover from solar damage and debris but it covers the tub from top to bottom. It also holds the heat so that saves money on keeping the tub warm. Very happy that I have this cover for my tub!

Our original heavy duty hot tub cover started to fall apart after nearly ten years. One side became water-logged and eventually like cement, causing the side to sink noticeably versus the other. We could not find a similar replacement without waiting several months and since winter was upon us we bought this cover to put over the original to hopefully stop further deterioration. This cover has suited our needs well and kept water from getting in. The wind only lifted a corner once in awhile but never the whole cover and it wasn't a big deal to reposition occasionally. The second picture shows the fading of the top vs the sides of the cover but that was not a show stopper for us. Our hot tub gets full sun until after 2pm. Well worth the inexpensive price for our needs.

This Is just what I was looking for 97" x 85" fits a hot tub 95" x 83" perfect fit I will order again when this needs to be replaced .

I like the fact it is exactly as it was advertised. No surprises. Fits well easy to use by myself. I would suggest this to anyone.
