I love the fact that it comes in a starter kit. It's digital and you have access to different systems. The apps are free. You get instant reading for results. I have problems completing colors on some readings and calculating amounts which with this system you don't go through that.
I have been looking to buy a digital testing set for a couple of months, this one seems like it's the most complete kit to cover all of my needs. I believe that even if I don't win it that I'm gonna purchase this kit as soon as I have the funds.
