This doesn't work! Don't buy Whip It
This doesn't work! I've gone through three of them so far and they all fail. You screw in the charge and it all goes out the nozzle immediately, along with most of the water. You set it aside for a moment and all of the remaining water and gas slowly leaks out of the nozzle, leaving you with a big mess.
I go through soda siphons more than most people because I keep giving them away to friends, so I have a lot of experience with various soda bottles. I bought this one because it looks like one I've never had problems with. This one failed, shooting all of the CO2 and water all over the counter. I figured it was a defective unit, so I brought it back to exchange for another. The second one had the exact same problem. I returned it and they gave me another. Exact same problem!
This soda siphon is crap, it doesn't work, don't waste your money on this.
And that five star rating? Chances are it's an employee of the company who has never used this. Just remember, I tried three of these disasters and they all failed.
