If you own an Amazon business this is a no-brainer. It's the equivalent of having locks on your doors or insurance on your car/home. Imagine a bodyguard constantly watching your valuable listings and informing you when something is wrong. It's priceless and saves you tons of time from constantly checking your listings.
I really like how it tracks keyword ranking movement. You can put in specific keywords and will get alerts when your ranking changes a certain amount that you specify.
The system also acts like a private security firm when it sends you alerts about buy box losses, suppressions, leeches, negative review "most helpful", star ranking changes, and more.
