I've been eyeing this but didn't want to spend $100. found it for 64.49 with prime. Just sharing just in case anyone else was looking. you can use this with all 3 apps (Perfect Blend, Perfect Bake, Perfect Drink). It measures as you pour and guides you step-by-step.
CCC: make with it what you will.
