I had used my old Vitamix for 10 years. this year I finally decided to get a new one and trade in the old one! the one Vitamix A2500 is Superb!! I love it! I use it every morning to make my green smoothie. Love the pre-set smoothie function that take the guess out of the game. 50 seconds and I super yummy smoothie! cleaning is super easy. I still want to explore the other functions! Plan to use this one for another 10 years!!
