My local home brew store could not provide me with one of these that worked. It was plastic trash that would not work with the ball lock they set me up with. I thought maybe it was a defect and returned to see if I could get a refund or exchange, and they couldn’t get it to work either, and a new one also would not work. This one is well-built, looks good, fits on standard bottles, has no leakage, and costs less than the name brand, plastic junk.

I have had an original carbacap that I have been using for quite literally for 15ish years. They were made of nylon and work really really well, annoyingly I dropped the water bottle after it was carbonated with the cap still in place and the pressure bump from the drop (I carbonate to about 70#) was enough to make it start leaking co2.They havent been available for years and I saw the many good reviews for this and gave it a try, honestly I was pretty skeptical. I have tried a number of different caps over the years and have never found anything that works as well and that old one. They were bought out a number of years ago and the newer versions arent as good being made from a plastic resin, the original company name was liquid bread, if you ever spot one somewhere snap it up.I was delighted to find this has worked really well so far, Ive only carbonated a few times with it and Ill edit this if that changes but Im very happy with it so far.The only criticism I have is the outside shape, the round outside makes it slippery and not easy to get on and off, but that wont stop me from using it. Ill just be occasionally annoyed when I do, but Im easily annoyed anyway...lol

I have had an original plastic injection molded one for over 20 years, still works. I needed a few more and found these stainless steel versions. Very rugged and well machined. They seal very well and it looks like a silicone garden hose seal works for the bottle-to-cap seal. These will last a long time. Using them to make lightly carbonated water, custom flavored.

Replaced a failed plastic carbocap with this.Works much better.Held off due to quality concerns, but the two I received have been great.

When we got the carbonation lid for our corny keg, we were trying to figure out a way to provide carbonated water during the 2 days it would take to charge a fresh keg, and found these (same brand). The idea of being able to take a bog standard 2 liter bottle and charge carbonated water in it was, TBH, mind blowing, so I decided to give it a try, in the hopes it would give us a backstop while the keg recharged.The cap itself is cut on the sides allowing you to use a keg spanner to tighten it up, a really useful feature for us with physical disabilities that make grip an issue.It works so well! One thing that we did though was to get some liquid tubing, and a pair of micro porous stones (Ferroday again). We hooked the tube and stone up, in the hopes we could get the micro porous stone speed, and easier to store standing up while it charged. It works well in both cases.So for 3, 4 hours of charging, at 35psi, we get a 2 liter bottle of carbonated water. Any short of a time doesn't seem to work, but I don't know if this is a limitation of the carbonation cap or operator error, as I've seen YouTube videos that claim less than an hour to charge a bottle.I'd recommend this, both for charging a 2 liter bottle before going out, or as we're using it, to make sure we have standby fluids. If you're using this alone, rather than with the upgrades I mentioned, remember to lay the bottle on its side in the fridge for the tube to be inside the liquid.

Overall I'm impressed with this. The ball lock coupler works well, the cap fits a standard 2L PET soda bottle and doesn't leak under pressure, and it seems well built. I am able to use it to carbonate water in a 2L soda bottle. BUT the barb included is NOT 5/16", it is smaller. A 5/16" ID hose slips right off of it. This is not a new complaint (check the Q&A for this item). I really wish they'd update the product description to be accurate. Now I have to buy a smaller hose.EDIT: the barb is 1/4" and holds on to a 1/4" ID silicone hose well.

Before I found these I was using the plastic model, but it started to crack after using it every day to carbonate 1-liter of water. These will last you a long time. The only thing I don't like is how heavy they are, but that's very minor and you can't expect a quality stainless part like this to be light weight. It's only an issue when my PET bottle is empty, and this cap makes it very top heavy and prone to fall over until I fill it back up. It comes with some replacement gaskets, but the part will outlast the number of gaskets they give you, so you'll eventually need to purchase some. Last week I noticed that my flat gasket was missing, and after a thorough search of the kitchen floor I'm assuming it went into the disposal. I spent a stupid amount of time searching for the right gasket on Amazon, but out of desperation I took one out of a garden hose and tried the fit. It's perfect, and could very well be the same type of gasket originally supplied. I bought a pack of 50 standard silicone garden hose gaskets that'll last me forever. The fit is perfect, as seen in my pics. I don't need the dip tube, so that's why you don't see it in my photos (it unscrews and saves me a little weight and makes the cap easier to clean).
