I bought this because of the variety I fix the bypass valve on my water softener.Great product Thank

The o-rings are adequate quality, most are good, a few are not usable. I ordered this specifically for the 28x3.1 o-rings. The label on mine showed 28x2.4. I measured them and they were in fact 3.1 cross section thankfully. For the price this is reasonable, but the quality control is certainly lacking.

Great kit. Wide variety of sizes. Just what I need for my project. Fast shipping and great value.

Lots of sizes and selectionGreat price pointIf this is what you need, it's good to have on hand

Great set! Very convenient.

He's our good quality rubber o-rings at least they seem to be. I haven't had any issues with them in the case is nice and it snaps shut nice and tight. Overall it's great for the price and all of your o-rings are labeled right on the case, their sizes. It's pretty nice

The rings are diverse, it doesn't leak and they're really strong, I love the picks that come in the case as they really help out if the rings are misplaced
