This is fantastic for 6 gallon glass carboy
I have a mini fridge for fermentation temperature control and a full size liquid lock will not fit. I wrap the carboy in a plastic bag in case of a blow over. I've never had this blow out of or be sucked into a carboy.

First Use report (so far)
I hesitated giving a numerical rating yet (but is required).  I wanted anyone else that has just gotten one of these to BE CERTAIN that it is firmly seated in the carboy!  After going through the process of boiling and all, making sure to keep things clean and sterile, we set the carboy aside with the new airlock, only to find it on the floor come morning.  It evidently built up pressure enough to dislodge the stopper before opening the rubber valve.  We're now waiting to see if this batch was compromised with airborne particles. Fingers are crossed.  We FIRMLY reseated this time and it's stayed.  Obviously it takes more pressure to open the rubber valve than to blow a bubble through water. I like not having to deal with the old style water filled airlock.
*Update! Have not had another problem. Works well.

OK to use with Plastic Carboys
I agree with the other reviewers in that I would *not* use this with a glass carboy since it is difficult to get it securely snug on a glass carboy.  It works fine with my Better Bottle but I limit my use of it to secondary fermentations.

Good for Better Bottles
I use the stopper inmy better bottle, but woul dnot use it otherwise. I like it because when moving a Better Bottle the bottle will distort making it easy to suck in the airlock fluid. With this stopper that is not a problem, but it does seem to allow more pressure to build up inside the Carboy. I probally would not use it in a glass carboy, just in the Better Bottle, and even then only after active fermentation is over.

OK, not great
This thing is ok. But you have to be careful. If there is active fermentation going on, it will blow it right out of the carboy. I also tried to use when cold crashing, somehow all the air got sucked out of my better bottle and warped it with this thing. I only use it during secondary fermentation.
