Pros
- The lowest price on an oval cover anywhere in the field — about $61 at 18×33, and $11 at 10×15 for a small oval
- Owners who know what they bought are content: "a reliable, seasonal-use cover for a budget… they consistently last the season without tearing"
Cons
- THE HEAVIEST CRITICAL TAIL ON THE PAGE — 126 of 681, nearly one in five — and it is about the cloth: "paper thin", "I've honestly seen thicker garbage bags", grommets straining or pinched shut out of the box, "had to replace after one season"
- The "8-Year" in the title is a word: an owner whose tie rings ripped in year three found the warranty "expired a month ago", and no maker warranty document exists off the listing
- Runs small: a 12×18 owner found the long side "too tight and did not wrap around", and an 18-ft owner's "kept falling in" — size up, and expect to weight it
- Its 15×30 was "Currently unavailable" on 2026-09-04, so the most common mid-size oval cannot buy this one today
The cloth: "paper thin", "thicker garbage bags", grommets straining or pinched together before installation, a cable that snaps, and a lifespan of one season that repeat buyers accept as the deal ("if you don't mind buying new each year"). It also runs small — a 12×18 owner's long side "did not wrap around" — and one 18-ft owner's cover "kept falling in".
126 critical reviews against a 681 base (about 18.5%); of the first 10 read, 5 describe thin cloth or grommet defects, 3 a one-season lifespan or an expired warranty, 2 a cover that ran small or fell in · critical reviews read September 2026
