I'm pretty sure I've had it for 25 years now. The way I figure that is that there was one in Total Recall, and that came out in 1990. It's worked great ever since then, and I think the main reason it's so sturdy is that there are no removable parts. It's just built well.
I've been aware for a while now that you can put wine in a blender to rapidly age it and improve the taste, and the results of a taste test on the show Hack My Life convinced me to finally try it. I figured if I liked the results, I'd probably want to do it pretty often, so I brought the Braun downstairs, along with a big Slurpee cup to blend it in. It really does work quite well! Franzia burgundy's our house wine, and blending it for a few seconds makes it taste like something that costs at least 5x more.
