High quality cover
Pros: Cover looks and feels of high quality material. I like the mesh underside which doesn't trap moisture or water in the cover. Lite weight.
The skirt hangs nice and low enough to keep debris and wind from getting in. Color looks great and the rounded corners match my tub perfectly based on the dimensions I provided.
I live in Wisconsin and temps this week were around 8-10F, the bit of snow we got remained on the cover meaning it didn't melt and the cover is providing excellent heat retention keeping the heat inside the hot tub. I opted for the 6" thick upgrade, a must have in cold climates to keep my energy bill lower over winter.
Cons: Minor one, the cover is about 2" bigger both length and width than my hot tub and I was hoping for a snugger fit of the skirt to the side of the tub. This may be by design to ensure it fits but allows a little gap for strong winds to catch, without the clips holding it down it could flip open.
Overall: If it lasts for many years I'll buy the same one next time.
