Review on Toolcool Aquarium Stream Thread Adapter by Dustin Keller

Well made and fits the patented lid of large beverage cans, but that's not the end of the story. You will need a few other parts to make the connection to the CO2 tank. Which I bought on the spot and called all the cities. It was another $14 for this adjustment and another nipple adjustment. Eventually I thought I was ready to go and then found that my 4 large tanks needed to be checked before they were full and they charged $20 each. Personally, I'm just frustrated that Soda Stream and (Costco, where I bought it) made it so complicated.
