Pros
- Highest review count (3,800+) of any solar cover in this roundup, the most-option for round above-ground pools

Cons
- 3 to 5 year lifespan is the shortest of the mil-thickness tiers, needs replacing sooner than a 12-mil cover
- Thinner material is more prone to puncture and UV degradation over a season of full sun exposure
- Round-only sizing, not usable on a rectangular or oval pool
