I bought a Ninja Express at my local Walmart, very reasonably priced. Use the coldest frozen ice possible,I find that if the ice is even the least bit moist/melty that the "snow" is all clumped up and chunky). Put in ice after placing the blade in. Put the lid on and hold down the button till you get the consistency of ice/snow you want. My preference is fluffy real snow like consistency . Then enjoy.
