I have tried to use a few of them and end up frustrated in one way or another with them (too much room given to something I never use, not enough room for notes, etc) so I just use notecards. One per pt. and put whatever I need on there. If the pt. stays longer than one notecard, I start another.
That's what i started doing too. Get's a little disorganized though if the patient has a long stay (and i tend to write big if i'm in a hurry), but it saves me time rather than having to recopy the H&P by hand 3-4 times, and if I need to present a patient at a moments notice, like at attending rounds or intern report, everything is right there. And because I write big, using those premade sheets from med fools was always a pain. It's the best method i've found so far, but i guess that's not saying much .
