I am a chef and had to give my old vitamix to my food truck. Missing my vitamix dearly I bought a new one for home and I took a chance on the ascent model. I did tons of research regarding the newest model with the auto buttons and the base model. I usually don't do anything automated so I bought A2300. So glad I did, while I can't speak for the newer models, the A2300 works awesome. I saved a ton of money buying it too... the new models are hundreds more. The ascent series have a new lid design which I love! It's so easy to snap right on. can't wait for the new accessories too. Very happy with my purchase!
