Input:
I bought this about 13-14 years ago, skeptical about how much I would use it and the plastic (nylon?) blade. Still have it and it's the most used appliance in the kitchen, make a shake every morning now for all those years and maybe one after the gym. Still going strong. No rust. Totally beats hand stirring or shaking a milk/protein shake.
