Bubbles for days
Works great in carbonating 5 gals of beer or sparkling water. And the included hose fits right over the post with no need to use a hose clamp.

Useful for small conical fermenters
Small but works well.I attached this to a silicone tube and 1.5” TC ball lock connected to the lid of my conical SS fermentation vessel. Easy way to force carb.

fine bubbles and resistant to nitrogen oxides
These produce a very fine mist of bubbles and seem to withstand nitric and NO2 gasses with a dozen uses an no obvious corrison. They are outstanding for ad-hoc nitrogen oxide gas absorbers. The main downside is the pressure required to achive throughput, several PSI, at the hairy edge of typical glassware.

Seems like no quality control - EDITED -
As with some others, mine was defective with all the bubbles coming out of 3 or 4 areas… all VERY large bubbles; almost like right out of the tube. ***EDIT*** I got a replacement, and it was much better… not as good as I’d like, but a solid 3.5 star, rather than the 1 star originally given.
