Never used one before. Seems like it will be better for frothy ferments than what I was doing before.

Does not fit 6.5gal glass carboy
I am usually a huge fan of morebeer but this DOES NOT FIT 6.5 GAL GLASS CARBOYS. It fits my 5gal great but not 6.5gal. I was looking for the blue carboy caps (can't find on morebeer anymore) as these fit 6.5gal glass carboys great. Someone else said it best...at a few bucks it is not worth returning but do not buy for 6.5gal carboys.

Not what I expected
Does not seal well for using CO2 to transfer from carboy to keg.

Does not fit
Disappointed to see it does not fit. Too inexpensive an item to return so I guess I'm stuck. You might try calling customer service for diameter size before ordering.

New hood does not fit properly
My older hood fit perfectly on better bottles. The new hood does not make an airtight seal with the better bottle, and the thermowell port is so tight that it is nearly impossible to get a thermowell in without keg lube and so far impossible to remove once inserted. The rubber compound on this one seems to be much stiffer than on my older carboy hood.

Does not fit snugly
Does not fit snugly, air leaks around the seal. Compared to my 4-years old hood, the plastic seems to be less flexible.

Snug fit and good quality.
Saw quite a few reviews on other sites about fitment issues. The ones I received from here for extremely snuggly. Almost enough to lift an empty carboy from the cap alone. Very satisfied with fitment.

Works great and haven't had a problem with them yet.

Nice product but a airlock with tubing as a blow off seems to be more secure.
Seemed to work ok but found air does leak around the seal. I wrapped package tape around the bottom of the cap and affixed it to the bottle.

Works great with thermowell and blow off tube
Used with thermowell and blow off tube. Excellent

Excellent for Blow Off Tubes
I have been looking for a better blow off solution for my Better Bottle fermenters and this does the job. Fits perfectly and doesn't come off like the stoppers do when they are wet with sanitizer and being pulled with a blow off hose.
