Review: Good product and good customer service - If you have brewed before, you know what these airlocks look like and how they work. These were good, and typical of this kind of product. What prompted this review was the good customer service. I THOUGHT the package came with only 2 gaskets but it turned out one had wedged itself in one of the red caps. So I wrote to customer service asking another be sent. They got right back to me with an "of course" and just asked that I make clear the product I was asking about (presumably so there were no errors in what I needed). I let them know my mistake and all if finished. But good customer service by the Onebom Supplier!
Review: Fermentation Airlock - These are very similar to the airlocks I used years ago homebrewing beer. They are far less expensive and not nearly as strong of a plastic as what I am used to but they work just fine. The grommets insert easily into a 1/2" drilled hole and once the airlock was placed in the grommet there was no CO2 leaking from around the grommet or where the airlock enters the grommet. So they do exactly what they are supposed to do. They are being used for homemade CO2 tanks for an indoor herb garden.

## Features

- ★WHY CHOOSE S TYPE AIRLOCK - Easy to use. During the fermenting process,it naturally occurring bacteria feed on the sugar and starch in the food to produce lactic acid.Fermentation helps make food easier to digest and often boosts its nutritional value.You can easily see the process. The cap don`t need the hole as the gases can escape from the gap.
- ★WELL MADE- The S-shaped airlock features 2 vertical chambers connected by a sort of drain trap. It does not suck liquid back into your brew when cold crashing.It`s strong and sturdy.You can use it for a long time.
- ★EASY TO USE - Fill the Bubbler Airlock with 1/2 or 1/3 water and insert in drilled stopper or grommet to vent gases during fermentation.It is the preferred airlock for secondary fermentation, as it is possible to monitor the pressure inside the fermenter.Package include 3 grommets. Pls order from other shop if you need the silicone stopper.
- ★WIDELY APPLICATION –Works great for home brew with a better flavor as it lets no air in but does allow for gases to leave. It can also work for fermenting vegetables like ferment cabbage to make sauerkraut.
- ★WORTH TO GET IT - All the ONEBOM products tested before pack it to desertcart. Click the “Add to Cart” Button and Buy with No Regrets. Just return them back if You Got Any Problem but don`t want to inform us.
