We have them in stock, (yes I am back from Russia) Just a PSA, if you have a bottle with a slow flow valve you'll want to remove the slow flow stopper on the valve. Drain your tank, unscrew the valve and locate the bolt on the bottom of the valve. With the EaZy you don't need it and the quick fill will work so much better without the slow flow stopper
