Review on Harding Swivel Spring Carabiner Shackle by Tony Suggs

Not sure if I have any bad ones but none of them worked properly. I couldn't even press the spring latch on one. It dropped 2mm at an odd angle and just stopped, unable to open the shutter. On another occasion I was able to push the shutter all the way down, but again it went down at an odd angle making it difficult to push, and the spring was noisy and didn't close the shutter very strongly. I wouldn't trust this to hold anything securely or last very long.
