Totally worth it!
[This review was collected as part of a promotion.] My hot tub came with a cover so I wondered if it was worth getting this one. It is totally worth it. The cover mine came with sits on top but the cover top comes with an inflatable insert to add to the cover to hold the heat in. That piece is about 2” too small all around the circle. This cover has what I call a plug top that fits perfectly like a plug or cork would work and then the cover goes on top and clips around the sides. The cover clips down almost to the ground, so it holds the heat in around the sides as well as on top. It also makes it so much safer for possible children that might try to climb on it. It definitely saves energy!
