There are so many slush makers but this one is exclusive to Vita's VLT.
You can get it for $25 by purchasing $20 more on Vita's Chrysanthemum Tea or Lemon tea at 7-11. Circle K and Vango.
I admit, I was too impatient on my first go so it didn't work.
You have to put it in the fridge for at least six hours!
