Review on Kenmore UB-1 4369591 Upright Vacuum Cleaner Belts, 2 pk. - Replaces 20-5240 and 20-5275: Essential Replacement for Optimal Cleaning Performance by Amanda Davis

First of all, these UB-1 belts are NOT made by Kenmore, they are unbranded replacement parts. If it was clear I'd pay a few bucks more and get the original. It's sad that sellers intentionally label an item as genuine when it's counterfeit. Revain really needs to crack down on crappy products. Second, it was too small, both required more stretching than I've ever experienced installing a vacuum belt, and both burst shortly after turning the power on. No I didn't catch anything, it was a vacuum cleaner standing on a clean workbench. I even watched youtube videos on how to install them to make sure I did it right and the belt life was less than a minute on each. two broken belts and went with a genuine OEM at a local Sears. Totally different (better) quality - it matters if your company name is on the product you sell. Save time and hassle just buy it from Sears, at least this UB-1 replacement belt kit sold by "Vacuum Fix" is not a genuine Kenmore product despite the description saying so and both belts failed within the first 5 minutes after installation.
