This was my second Magic Bullet purchase because I realized how devastated I'd be if my first one stopped working. I drink Bulletproof coffee (my version of it,) and I know you don't like us to whiz up hot stuff...but I do...and I've learned: no more than 30 seconds, and remove the lid immediately (so pressure doesn't build.) I also, of course, like to whip up smoothies with frozen fruit and non-dairy milks. Love my Magic Bullet.
