It worked
Did what it was supposed to do....

It will make your beer stink of rubber. Don't use it.
I got a few of these about a year ago for brewing a Flanders red ale. I did a 10 gallon batch, split between two fermenters in the same space with the same yeast. The only difference was the stopper; one used this rubber one and the other used a silicone one. Last night I pulled some samples. The half with the silicone stopper was very nice, with notes of cherry, leather, and mild funk. The one which used this stopper, however, reeked of rubber. It was not the same rubber aroma as autolysis or yeast stress. It smelled just like the rubber stopper. The same flavor was present in the sample which I pulled, even after I let it sit in a glass for half an hour. I switched out the stopper for a silicone one, and hopefully the rubber character will go away, but in the meantime, it looks like this shoddy bill of goods ruined a batch of otherwise excellent beer.
