I think I understand. The site and pictures don't provide much description, but from your post, is that red button with the person's thumb on it the "Burst of Power," and then the on/off/increase level button above that? If that's the case, I can see why you don't like it - seems like it makes it difficult, if not impossible, to turn it on without turning it way up at the same time.
And I agree, it is big for a hand mixer.
Have you tried WalMart or Target? A lot of times they have them set out on display so you can at least hold it before you buy it to see if it's comfortable to work with.
