Nite Ize S-Biner SlideLock Locking Stainless Steel Carabiner (Black, #2)

Well made, good locking mechanism, ideal for rucksack strap

I brought these specifically for the slide lock, as I have the tendency to loose items when I hook onto my backpack. Traditional carabiners break easily. This Nite brand is top quality, a bit pricer but very reliable. I secured my travel neck pillow onto my backpack for the whole duration of my trip and it never came undone. I love the side lock which adds another layer of security. The size is a little large but is fine. I have also tested with my water bottle and it holds it well.

I have several S-Biner from Nite Ize and they are robust and with a wide span of usage. This S-Biner with slidelock fulfils my expectations completely.

Bought this as an extra measure of security on a backpack zipper. Works well and I'm sure that if someone decides to try and help themselves to my backpack contents I'll notice.

Very secure and lockable perfect for my rucksack. Worth the value in money.

Small but really handy, well made too.

After ≈ two weeks of holding a water bottle to a bag (high use though well under the 10 lbs limit), the gates broke off. Before this, the gates did repeatedly lock on the wrong side of the bar which required fixing with brute force. I'd just get a normal carabiner.

I use this clip on my keys. The lock has keep the side with the keys secured whilst the other side easily clips onto my bag. The size is around the same as a smaller key
