I am currently on week 4 of the Beta disks, and I am loving these workouts. I am a busy mom and student, and I have had trouble losing weight after baby #2 (let's not talk about how old that baby is now!) So far, I have lost 12 lbs and over 14 inches all over my body! I've also dropped two pants sizes. I had almost zero strength in my abs after having kids, and I'm getting that back with these workouts.

My experience with this knife has been all positive. Out of the package it was razor sharp with tight tolerances. Other reviewers commented on some amount of play in the blade, but this isn't the case with mine. And the blade launch feature works great.
