Excellent product, good price Review by Rich

I have five of these now for use in my 1-gallon fermenters. They work like a champ, they're easy to clean, and they're inexpensive.
I like them better than the bubbler airlocks. They're easier to clean and work better for me. (Posted on 1/22/14)
Best 3 piece Review by Nick
Rating
I had a number of air locks, they all work. This one had two better features: first the small cross in the bottom seems to break bubbles when close to boil over, second the inner piece is balanced better. Good enough that I got another on the next order so the others are back-up. (Posted on 1/16/14)
Great airlock Review by Casey

Fantastic airlock. Never had a problem with leaks or contamination. Highly recommended (Posted on 1/15/14)
Double use airlock Review by Robert
Rating
These work great for me. If foam from an extra active ferment gets into one, I replace with another, without the cap and float, and jam tubing into the air channel on one end and other end in a jar of sanitized water for a nice blow off arrangement.

Easier to clean than the alternative style and fits the one gallon fermenter caps well.

Wife got me several extra of these for Christmas. They are cheap and well made, and always good to have extras. (Posted on 12/29/13)
Great airlock, easy to clean and see. Review by Eliot
Rating
This airlock is easy to take apart and clean. It works really well. I brewed a beer with very active fermentation and was able to see the airlock had clogged. Had another identical unit, sterilized it and witched them. Beer turned out great. Should have used a blow off tube but was not called for in recipe. (Posted on 12/5/13)
needed a few extra Review by Michael

I needed a few extra air locks to brew some 1 gallon batches and I like these three piece sets they are easy to clean. (Posted on 11/24/13)
Works as advertised Review by John
Rating
I have a few of these and they work great. I definitely like them better than the bubble airlock. I have had a blow out with this model but it was on a 1-gallon brew and not enough head space. Gunk can get into the bottom of the airlock and plug it up.otgerwise, works as advertised. (Posted on 10/17/13)
Better than the rest... Review by Jordan
Rating
I've been using these for a while now, they are easy to sanitize, they break apart and are easy to clean if your fermentation was a little more active than you thought it would be and the best part is, it doubles as a blowoff tube base. Take the cap off and the float lock out, put some 1/2" tubing on the air channel, and just drop the other end into some water or star san. I think I currently have about 15 of these, not a one has broken on me yet and I will continue to buy more as the fermenter count increases. (Posted on 10/3/13)

Best airlock avalible Review by Bill

I have tried all of the airlocks that Northern Brewer sells, and this is by far the best airlock that they carry. Its durable and a breeze to use and clean. (Posted on 9/20/13)
Easy. Convenient. Works. Review by Brian
Rating
It all fits right together and breaks down quickly for cleaning. Double Bubble may work for some, but I've had bad experiences with water being drawn back into the brew. I don't have to worry about that with a 3-piece. (Posted on 9/9/13)

Cheap as these are, there's no reason not to have a few extra on your shelf at any given time. Super easy to use and clean. (Posted on 8/8/13)
Great Job NB Review by Brian

My original order of this item arrived cracked most likely due to shipping and the guys at NB swiftly sent me out 2 new ones at no further cost to make up for it. Working perfectly. (Posted on 7/24/13)

Best option for airlocks Review by Mike
Rating
Easy to take apart, clean, and fill. They are plastic so handle with care when removing from a stopper. Buy a few - they are cheap and get the job done! (Posted on 5/1/12)
It does what it should Review by Binxy
Rating
Bought 6 of these when I was in the shop about a month ago.
There cheap, and if I break one I have some back ups. It's plastic, so I don't expect them to last forever. Hence the reason for the back ups. (Posted on 3/23/12)
The only one I use Review by Do The Home Brew

Never had any problems, or breakage. Use star san solution or some hard liquor as an extra level of protection from infection. (Posted on 1/23/12)
Potential Review by Mike
Rating
Not to discourage anyone but it is plastic. Though it was mostly my fault trying to twist it out of the rubber stopper when transferring to a secondary fermentor it actually snapped right at the base so it couldn't be salvaged. Plan B was to use a makeshift blowoff tube to save the batch of beer.

I think I'm gonna give glass a try next time around. (Posted on 6/23/11)
Better Bubbler Review by Jeffro the Pagan
Rating
This style is much better than the "tripple ripple" style. They tend to dry out if used for long times (months), so keep an eye on them. (Posted on 3/30/11)
Buy a few Review by Brian
I have to say these are superior to the double bubble air locks. These are easy to take apart, easy to fill, easy to clean, and they just work. You can't go wrong. Get one or two extra, just in case. (Posted on 11/12/10)

This is the best option for your airlocks. Easier to clean, much less risk of backwashing. I have not had any problems with mine drying out, and it's easy to just add a little water if necessary. I'm throwing away my bubbler style airlock that came with the starter kit and replacing with this. They are definitely worth the extra few cents. (Posted on 6/18/10)
