I use a Hamilton beach personal blender that ranges from about 10-15 dollars. I'm on my third one. The blender cups last about 18 months of once or twice daily use. The seal just sort of wears out. I do wash in the dishwasher. My dh has a nutribullet, but I still prefer the Hamilton beach! I use frozen fruit every time. I think it is an excellent value and it has good reviews. The smoothies turn out great!
