Anyone used them?

I just tried them and was impressed, a great way to keep some sweetness in a cider without lactose or back sweetening.
The only down side was the last two glasses were a little flat.

What exactly are they. Tipsy?

Just tops to put on juice containers that vent out Co2 but also let enough pressure build up to carbonate the drink.

They were given to me as a gift.
Now all I have to do work out the best time to stop the fermentation by putting in the fridge, but thats half the fun.
