Works great – OB Wheels Review

I don’t understand all the negative reviews. You put in the LMP or the ultrasound Dating and it tells you what you need to know. Simple as that. Tells you when to use U/S vs LMP also. The “wheel” is clunky and kind of pointless if you ask me. I always just use the calendar based calculator.
