## Customer Reviews

### ⭐⭐⭐⭐⭐ Robust
*by M***E on January 25, 2026*

Quality carabiner as usual with this company

### ⭐⭐⭐⭐⭐ Safe, Strong and best carabiner for Rappelling
*by D***M on November 9, 2025*

Awesome for rappelling, locks up good, has plenty of room for rope wraps and is very affordable. The round bar design allows for smooth rope operations.

### ⭐⭐⭐⭐⭐ Five Stars! It worked very well for me!
*by M***S on November 5, 2020*

Well my purchase of this wasn’t for what you think. You see, I bought this black diamond carabiner because I wanted to propose to my boyfriend in a unique way. We hike often and went on a trail that was so terrifying (to me, who is afraid of heights) that I kept saying I needed a carabiner for support to attach to the cables on the trail. (The trail had ladders too. Terrifying for those of us who aren’t rock climbers). Fast forward a few months, and I decided to propose to him (he had asked before but I wasn’t ready). I wanted to propose with a diamond, but also wanted to be original. This carabiner did the trick. It even has “Black Diamond” stamped on it. I asked, he said yes, so we will take the plunge. With the awesome support of this heavy duty carabiner, of course. Five stars, this definitely worked!
