I bought this about a month ago and it had started leaking from the bottom. I only use it about two to three times a week so it's definitely not from over use. I'm also careful not to over fill it. I've noticed it's leaking around the screws on the bottom of the blade housing. Also, when it leaks and gets inside the base there is no cleaning it without taking it apart. Other than that, I really liked it...but I wouldn't buy it again!
I purchased this item last July, but really didn't start using it 'cause I didn't know what to put in it. In the beginning, I put a lot of stuff in that just didn't result with such a great flavor. Now, it's my go-to appliance for a great, fruity, wonderful and healthy beverage. It's so easy and great.
we previously had the black base model (600) and this 900 is great. We sometimes put in frozen berries or slices of frozen beets. This machine does a great job of pulverizing the food. Can LEAK if blade unit is not screwed on very, VERY tight. It's a mess to clean up juices that have leaked into the base...room for improvement.
