These are great cord locks. They are well built, feel solid and hold cord like they should. I have had several cord locks that feel like they are going to pop apart and have actually had the spring pop out. Not these. They are very well made. I'm very happy with them and would buy them again!

Great product, perfect size and the price was excellent!

I was surprised with the strength of the springs in my examples. I've used so many comparable cord locks on cheap laundry bags and those throwaway "backpacks" they give out at expos. You can always pull the cord out with minimal effort. Instead, these locks are what those always wanted to be - strong and reliable. I've taken to making my own bungee whips out of them (picture)

Excellent locks, with many applications.

Bought these for the sole purpose of using with Goruck masks. Instead of having to tie it on, just gotta squeeze and tug. Mask no secure around head and neck with ease.

Makes life easy when a mask is required.
