The great thing about Amazon is that you can read other people's experiences before you make the same mistake.
I had been eyeballing the Vitamix for a while and even though they offer the periodic discount at my local Costco it's still almost $400 for the thing. When I saw the commercial for the Health Master (first from Jack then later from Montel) I thought "looks like a Vitamix, cooks like a Vitamix, it must be almost as good but cheaper than a Vitamix". Boy was I wrong.
Leaking, yes. Rusting, yes. Poor quality, yes, yes, and YES. And one thing the other reviewers didn't mention, it is insanely LOUD! I honestly think you would be better spending that money on just a good quality blender if you don't want to drop the big bucks for one that actually does all the things that this one claims to do. I ended up returning it (no, they didn't pay the shipping...should have bought it from Amazon) and getting a Vitamix instead. It was like day and night. There is no comparision.
Save yourself the money and headache, skip the Health Master.
