All benefits, no negatives!
First let’s state the obvious here theses not for climbing or for situations where product failure is an option. A high-strength polymer carabiner that doesn’t clank, rattle, scratch, corrode or is heavy. These are so good I have four of them and have given several of them as presents. I use them on the outside of bags and rucksacks and to hold bunches of keys together. They’re ideal for holding lightweight objects or accessories. Plus, a benefit is when you’re travelling through security/x-ray they are a lot less obvious and ominous than an equivalent metal carabiner.
