Summary: The jar will spin itself loose if you don't hold on tight. The jar is very heavy, and if you break it it costs $45 to replace. Unfortunately I did break mine trying to wash it. About a year after purchasing the blender the blade assembly locked up and I had to pay $25 plus shipping to replace.
Summary: I have used it to make smoothies and pancakes and it works seamlessly. Absolutely love this product. I haven't had it for very long yet, so I cannot comment on long term use, but so far, so good.
Summary: I have had this blender for over a month now and have used it several times. I mostly use it to make smoothies. I have had no problems so far. It takes a while to crush the frozen fruit and I sometimes have to take the lid off and move the fruit around, but the blender is solid and does not 'walk' or move, even when doing tough jobs like crushing frozen fruit. It fits very compactly on my countertop and looks great! It comes apart and is easy to clean.
