I've always bought Osters, something I picked up from my mother because she still has her blender that's easily 20 years old. I like making smoothies and had a single serve cheap thing that worked for me.  When the motor on my last Oster died I thought this was perfect because I wouldn't need 2 appliances to blend small and large items. I love my blender but the smoothie cup is flawed. I've had this blender over a year and I love how it makes my smoothies but the cup had a crack in the area just below the threading within in 2 uses.  Food gets stuck and you can't clean it. I've even gone so far as to soak it multiple times to make sure mold doesn't grow in the area. I'm disappointed that I can't replace the cup and based on some of the other reviews this flaw is not as rare an occurrence.
