    Twin Bubble Airlock and Carboy Bung (Pack of 2)

    • Cheap plastic, they have cracks in them very quickly
    • Works great, handle them gently though, definitely not the most robust plastic and can imagining them breaking if you pull from the bung to forcefully
    • Only concern is the bottom corks are also hard plastic
    • Seems like the plastic is just weak and brittle.
    • What does bother me is the fact that the plastic they're made out of feels somewhat brittle and, dare I say, a bit cheap (which is why I think the one broke in transit)
    • Cheap plastic stopper pops out of 5 gallon carboy with minimal pressure.
    • The plastic is very hard, resulting in the bung just working its way out of the neck, and falling out of the carboy and onto the floor.
    • The bungs are a hard plastic and not rubber, so they really don't flex or fit in anything.
    • I can't tell if these are glass or really hard plastic but they are solid and will hold up for whatever you're making.
    • Very clear plastic with a nice cap with small holes in them
    • These are plastic, which by itself is not a problem, except the plastic is brittle.
    • The product came with inexpensive hard plastic corks that are not very flexible and easily slip out of the bung
    • It's more of a hard plastic then a rubber
    • It is made of hard plastic and not flexible
    • I plan on jerry-rigging them the way some have done, or drilling out corks to use in place of the hard plastic plugs
    • The plastic is too rigid.
    • Like plastic
    • Plastic is safe to avoid cracking or splintering the plastic maintaining its transparency. . . .
    • At first the plastic felt flimsy, but i dropped one of
    • The product came with inexpensive hard plastic corks that are not very flexible and easily slip out of the bung
    • Great product, the double chamber is perfect for creating the most secure airlock possible, made of some pretty strong clear plastic and the stoppers fit perfect in my 5gal carboy
    • Made of hard plastic, not rubber has no flex ability to be used as a stopper.
    • The stopper is made from hard plastic.
    • It's a rigid plastic that's somewhat hollow
    • The plastic is very hard, resulting in the bung just working its way out of the neck, and falling out of the carboy and onto the floor.
    • Caution - the 2 airlocks have a very defined and harsh plastic mold line running from top to bottom.
    • These seem to be almost like hard plastic and don't push down into my 1 gallon carboy mouth very far.
    • Seems like the plastic is just weak and brittle.
    • Broke one just getting it in the bung, made of cheap plastic, bung is large
    • The plastic is very brittle
    • Hard plastic won't fit into a 1 gallon carboy.
    • The bung is solid and works well, the air locks are really cheap plastic and one broke the first time I tried to insert it
    • The base was far too rigid to fit in anything, the clear plastic bits themselves were fine, but the bases weren’t.
    • The caps are clear plastic with a number of small drilled holes.
    • While I appreciate the product, packaging, timeliness, and sturdiness, the stoppers are harder rubber/plastic that what I'm used to - a "rubber stopper" is rubber but these are a bit harder plastic and therefore don't seem to have as much "grip" as rubber.
    • Didn’t even get what was advertised terrible plastic piece of shiiiiiiit
    • As others have mentioned the bung is a soft plastic not extremely flexible but enough to fit into a carboy and hold a seal.
    • The stopper is a rigid white plastic that doesn't flex
    • I ended up buying different bungs because the hard plastic ones didn’t fit snuggly to my 1 gallon bottle
    • the bungs appear pliable, but are a rigid plastic with very little give
    • Plus the airlocks are extremely thin plastic, and probably will crack and split within a few uses.
    • They're not rubber, more of a soft plastic.
    • These are great in theory, but they really need to be handled only with the gentlest of hands because they're so fragile, made of very thin, brittle plastic
    • Don’t waste your money and effort in this piece of junk as it will not stay in your bottle top!
    • it works as it should.
    • Works as you expect
    • Work exactly as I’d hoped.
