I bought 3 of these. I know carabiners. Many types out there, alot of hype, alot of junk. For under $10/ea I get climb rated, super light, slender (nicely slippery where it counts). My #1 use for biner-1 is holding my keys, serious business yes? This biner offers extreme dollar/value. Many biners stink for the purpose of carrying keys, this one excels mostly. I modified #1 by filing down the pin that protrudes at the opening. I like fast deployment. This easily done mod helps the biner slide in/out easier without affecting its security. I know because I’ve relentlessly tested it. Nice. The other 2 will be used just about anywhere. Highly recommended as a true multi-purpose, low profile/weight, yet very capable biner.

Strong and durable, the spring clip is very strong, the carabiner itself is amazing. Great price on a great product

I'm not sure if I will ever need a carabiner that can support almost 5000 pounds, but it's nice to know it's there if I need it. The carabiner is lighter than others that support less weight and is the perfect size for a variety of uses and a good price for what it can do. I plan to use it for hammock camping. A+ customer service as well!!! I've been a fan since I first encountered SM on Kickstarter.
Any chance we could get a smaller, lighter carabiner that holds 1000 pounds, which would be even more suitable for hammocks?

very nice light weight and strong carabiner. i have 8 of these for all my hammocks, never had an issue.
