Query: WORKS great for mixing formula!

Instead of purchasing Dr. Browns Mixing Pitcher, I went to Ace Hardware and purchased this for $10. I had to write measurements on this (why I put 4 stars instead of 5) but technically this is not for baby formula and all other powders may be pre-measured... Works great to have bottles ready to go in the fridge! And im sure works great for any other drinks as well!
