Hamilton Beach Personal Blender for Shakes and Smoothies with 14oz Travel Cup and Lid, Black (51101AV) | 1 Jar

Pros: Just the right size for an individual serving, powerful enough to blend frozen fruit, less expensive than many similar products Cons: The blades are built into the bottom of the cup. The cup will start leaking around the blades, getting worse with use, until it leaks so badly you can’t use it any more. I’ve owned 3 of these. The first one had a round cup (newer ones have a square cup -bad design- fruit gets caught in the corners) and I loved it. After about 2 years the leak started and the cost of a replacement cup was almost as much as a new blender, so I bought a new one. The 2nd lasted about a year. I looked at other blenders but was put off by the prices, so (stupidly) I bought this model again. It has already gone bad after less than 60 days. This time I just went with a different brand and paid what I had to.
