So far so good - nice quality and expect them to last a lifetime with user maintenance. Good step up from the cheap plastic disconnects.

Looks to be built well and they are stainless.

I have a small 5 cf keezer in which I had expected I would be able to have four taps by stacking a couple 2-1/2 gallon kegs, but I failed to account for the space consumed by the upward sweep of most ball lock disconnects. This was exacerbated by my use of in-line GovReg secondary regulators, which effectively add another few inches of length to the stem of the gas disconnects. Torpedo disconnects to the rescue! With the combination of their compact design and right angle hose connection, I actually can stack those kegs and close the lid! A key is that the bottom keg should be a Torpedo keg, because their handles are designed with stacking in mind, so it's quite stable.

Also, these are nicely made disconnects. My one complaint is that you need a very large Allen key to remove or tighten the cap for deep cleaning or servicing. I don't presently own one that large and I have a large assortment of both SAE and metric Allen keys.

As another review mentioned, this solves my issue if being able to put things (stacking smaller kegs, sheet pans) on top of my kegs while still connected in my keezer. Sometimes I use my keezer as a backup fridge for larger things. Normal disconnects will likely leak with any weight applied due to their design. These should also last me pretty much forever. Good quality
