HERM SPRENGER - ClicLock Quick-Release Buckle - Stainless Steel

makes using the prong collar very easy, just clip/unclip. I found trying to use the collar without this quick release almost impossible.

This is very helpful for easy on and off! The cover does tend to slip off completely if you're not paying attention while clipping on and off, but as long as you pay close attention to it, it's no problem at all. Even if it comes off completely, the clip still works just fine.

Looks nice Can’t use it but looks good

Looks nice. Have not been able to use as won’t work with the intended. Ordered something else it’s just sitting not used unfortunately so idk.
