Review on Transform Your Vitamix with the Personal Cup Adapter - 61724: Enjoy Single-Serve Convenience! by Boss Spangler

Great stuff. This is a solution for owners of older Vitamix machines that are not designed for single-serve beverage cups. I don't understand the negative reviews as it is easy to use and easy to clean. I ordered 4 more cups so I would have enough as I drink a smoothie every day. The only negative (if you can call it that) is that it's a bit heavy (because it has metal gears) and I'm not sure why they made it that big just to add a cup. Maybe that's because he's firmly on base, which he is. Works like a charm and I'm thankful Vitamix made it because I didn't have to buy a new machine. My current car is over 10 years old. Just try it yourself. It is great!
