Made the switch due to new carboys and just as good
Had a bunch of the blue handles, but when I bought several new carboys they had only the smooth neck, so I got a couple of these. Now I wish I had purchased at least 2 more. Makes carrying carboys much easier
I've used these for years, and I haven't had one fail. I consider them an essential safety feature for glass carboys. I've recently moved to Better Bottle carboys, after a scary glass incident, and these work equally well with these.
Moving an empty carboy, you just use this but full you want to support with one hand on the bottom as well due to the weight and stress that would be applied to the neck if you just used the handle when full.
