2 of 5 Hard plastic September 4, 2020
Reviewer: Monty from Dutton  
I bought one years ago and it was a supple, excellent sealing silicone.  This one is a harder, less flexible plastic, that only seals the carboy mouth when it is pushed down.  Not very useful at all.
:(

2 of 5 Doesn’t seal well January 26, 2020
Reviewer: Matt from Airdrie, AB Canada  
I’ve purchased these in the past and they’ve been great.  I just bought 2 more and the plastic is very stiff and doesn’t stretch at all so it will not seal tight on the carboy. Need to tape it down to keep a good seal.

1 of 5 Works well at first, but ... November 23, 2017
Reviewer: JP from Qu├ębec, Canada  
Bought 4 of these for my carboys to use with blow-off tubes during primary. First use everything went well, but after only a wash in an alkaline solution they lost their air tightness (no more bubbles coming out of the blow-off tubes, all the CO2 went throught small gaps of the carboy cab). I do not recommend buying these.

4 of 5 Works great with small addition October 11, 2017
Reviewer: Scott MacDonald from Sudbury  
I bought 3 of these for 6 and 5 gallon glass carboys.  Transferred wort into 6 gallon carboy put cap on and inserted air lock.  It didn't seem too snug but left it over night.  Next morning fermentation was well on it's way but air lock wasn't bubbling.  Went to Canadian  Tire a bought three 2" pipe clamps.  Put one on tightened a few turns and bingo air lock started bubbling.  I just have to find a thief that will fit the the second hole.

2 of 5 Not tight at all July 28, 2017
Reviewer: Jesse from Windsor  
I bought 2 of these. Shipping was really fast but 2 cost 17 bucks after shipping cost. And they don't sit tight at all on my 6 gallon carboy. Waste of money for me. I liked the idea though
