What customers say
This cover is valued as a budget friendly, entry level option, primarily due to its generous overlap that simplifies installation and debris blocking during winterization. Customers appreciate its initial effectiveness and competitive price point. The main drawback centers on durability; many users find the material degrades significantly after only one or two seasons, especially under harsh sun or weather. Consequently, it is often viewed as a short term solution rather than a multi year investment. While it successfully protects the pool for one season, buyers should temper expectations regarding long term resilience. Proper water management techniques are noted as essential for maximizing its limited lifespan.
