Hot Tub Bubble Blanket - 7x7 FT 16-Mil Square Pool Spa Solar Cover | Heavy Duty Floating Heat Retaining Thermal Blanket for Insulating Solar Heating

It has protected our spa from the sun, reduced the chance of algae and helped us control chlorine levels. I'm sorry I didn't purchase this sooner! Our custom spa is a D shape and this insulating cover was easy to trim to size. It also seems very durable. The bubbles in the cover are like very heavy duty bubble wrap and simply float on the water. Although it just slides on/off the water easily, it's so big I found it a bit difficult to align while putting it back in place.

Received it quickly. I got exactly what I ordered and it was very easy to cut it to shape. So Happy!

We have a 6ft kids pool. The intax cover it came with had holes in so use this under to keep dirt out of the pool and heat in. Durable an sure it will last longer than one summer

Size is accurate, seems to hold in heat, just purchased so will have to wait to see how durable it is but it appears to be good quality.

Fit and works perfectly
