I needed a cordless blender and though I'd go with a semi known brand name instead of an unknown. Wish I'd picked any blender but this. The blender doesn't fit on the jar great. You really have to make sure the threads line up just right, sometimes having to do it 2-3 times. It doesn't hold a charge for long. If you're lucky you can get 3-4 smoothies out of one charge. Not good when you're looking forward to breakfast and the blender doesn't work. Guess I'll stick with the magic bullet until I can find a cordless one that's worth the money.
