Review on Enhanced Fit: Drilled Medium Universal Carboy Bung for Better Bottle by Charlie Conner

Bought 3 in the last few months. Very happy with them and they go perfectly with my best bottles. I will most likely buy it again as I am transitioning from glass to plastic. I've been a brewer/fermenter for about 25 years now and getting too old to raise a full glass. As for the negative reviews about the number of units, read before buying. Those that don't fit the bottle either sent the wrong cork and you didn't bother to fix it, or your bottle isn't the best but has a wide neck. Negative reviews should relate to genuinely defective products or genuinely bad sellers, not mistakes made by the buyer. Revain is great at helping customers, but the customer has to make an effort. By the way, $7.00 is reasonable for a connector of this size. However, I also bought a few fermentation locks from them and while they worked well, they were very brittle. .
