...more than 20 years ago. It's still working like new, and it changed my life to the extent hat I just purchased a second 5200 for a vacation home. Besides the refrigerator, the Vitamix is far and away the most used appliance in my home. Some years ago I lost 40 or 50 pounds over a period of months by using the Vitamix dramatically to increase my consumption of fruits and especially vegetables. Normally I'm not a fan of vegetables unless they're raw and drenched in blue cheese dressing, which kind of defeats the purpose if you're interested in healthy eating. But this machine blends any combination of any of them in as many different ingredient combinations as you can dream up, creating an endless variety of perfectly liquified vegetable, fruit, and vegetable/fruit beverages which make getting a full day's supply of things like spinach, kale, broccoli, carrots, cauliflower, peas, lima beans, etc. etc. etc. easy to swallow, very tasty, and so widely varied so they just never become boring or routine. Add protein powder (I particularly like 100% pea protein powder) and this becomes a daily breakfast that hits all the day's recommended vegetable intake requirements and usually holds me til dinner. Two decades ago the sticker price made me reluctant to try it. The reviews then convinced me to try. It was the best money I've ever spent, worth every dime. It operates now just as smoothly and effectively as it did then. The only change I've made was to invest in one of the stainless steel containers a few years ago b/c I found the plastic one a little difficult to keep perfectly clean. (You don't want to put it in a dishwasher.) But the stainless steel version cleans up thoroughly by using a half cup or so of water and a drop or two of dish detergent and processing it for maybe a minute. If you're on the fence, get off it. You're not going to regret this purchase for a minute. Your grandkids could very well inherit it and I'd be surprised if it didn't work just as well then as it does now. I don't know how they get this quality and durability at *any* price point.
