Review on CD5050 Thumbscrew Core Depressor Component by Jeff Leu

I bought 2 and both O-rings fell out after use. They fall out too easily and I've already used the two that come with the kit so 4 are lost together because you put them on and when you disconnect they fly away! A good product if the O-rings remain intact. I bought another one for o-rings. This time I think I'll superglue it.
