Great, affordable little airlock kit
Great little kit for brewing. I was worried about the silicone bugs vs rubber but it turns out they're actually really nice, without the rubber scent that come with the rubber bungs. I use these quite a bit and love em. Great price for this little kit. I'm really glad they added the little rubber pieces to place into drilled out lids and caps to add airlock to containers that weren't meant to be used as fermenter.

Was Only multi size pack I could find,works great
5 pk of bungs worked great, I was sick of measuring carboy necks, I have 4 that all take different sizes , this solved my problem,5 sizes in one pk, they are also nice rubber that stays put, not like those slippery silicone ones that fly out of the carboy. I Just wish they put a 5.5 in too, ( for 5L Italian carboys)

Work as intended
Have bought these twice. Good quality, have zero complaints about these. Had to do measurements to make sure I bought the right size. Airlock fits tight and secure tightly in the carboy. Have noticed if the inside rim or the rubber is wet they tend to slip out of the carboy. Can be solved with making sure those are dry or taking a rubber band and wrapping around the finger loop and over top of the stopper. They are a little pricey in my opinion but should last a lifetime.

Clean and work perfect.
Stoppers work beautifully and price is right. I always seem to find the odd ball sized 1-gallon jugs. Seal is perfect. Item has clean edges without balls of material like some brands.

Wine stoppers.
I am new to wine making. The listing gives size by number. I need a larger bung, and it was not in the pkg. If the ad had shown size by a ruler or metric, I would not have ordered this pkg. However the product is top quality, and I will keep them to possibly use for other things.

Great for shampoo, too!
I've ordered from this seller 3 times. All 3 orders have come quickly, and have been exactly what I expected. I use them in gallon and half gallon bottles of shampoo for my dog bathing system. They work perfectly!
