How to read a Showdown Score™
The only score that counts how often a product breaks, not just how owners feel about it.
- Three parts add up to the score: what owners rate it, how often it fails them, and whether a credentialed tester backed it.
- Bands: Exceptional 8.5 and up, Excellent 7.5, Very good 6.5, Good 5.5, Fair 4, Poor below 4. Every score is dated.
- Price, the warranty and what a link pays us stay out of it.
Fair
Fair is 4.0 to 5.4.
Amazon says 4.1 stars. We score it 5.2, Fair.

Pros
- The cheapest cover here from an actual pool-cover company, at about $71 for an 18×33 — and the only oval line whose rating base (4.1★ across 1,559) is oval owners only, not rounds pooled in
- Every common oval size on its own ASIN, 10×15 to 21×41, with the same 8×8 scrim and 4-ft overlap at each
- Robelle publishes what it is made of — 8×8 scrim, 2.36 oz/yd², UV-treated — where the fabric covers publish a denier and a marketing claim
Cons
- One to two seasons is what owners report, and the tail says so bluntly: "did not even make it through one season", "need to get a new one every 2 years" — and the warranty claim carries a $25 shipping fee owners did not expect
- THE WARRANTY TERM DISAGREES WITH ITSELF: the Amazon listing says 10-year, Robelle's own tier table puts the "Super" grade at eight years, pro-rated, and voids it for snow, ice, tree limbs and a cover "not the correct size or shape for the pool" — read it as a discount schedule, not coverage
- A 15×30 owner reports it "barely fits" with "no 4 foot overlap" — if your oval has a wide resin top rail, order the next size up (the buying guide explains why)
- It is cut for ovals: a rectangular-frame owner found it "does not cover corners" — if your pool has corners, this is not your page
Lifespan, measured in seasons: "did not even make it through one season", "need to get a new one every 2 years", "at 7x7 scrim it is thin", holes after the second winter letting rain through into a green pool. The warranty is the second theme — a claim costs a $25 shipping fee owners did not expect, and outside tears are excluded. One 15×30 owner got no 4-ft overlap; one rectangular-frame owner learned it does not reach corners.
143 critical reviews against a 1,559 base (about 9%); of the first 10 read, 6 describe one-to-two-season lifespan or tearing, 2 the warranty's fee or exclusions, 1 a 15×30 that barely fit, 1 a rectangle it could not cover · critical reviews read September 2026
