I like that it is easy to use, very effective in detecting food allergies when used with an IgG test kit (like Quixtar).
It's also not expensive compared other options out there for testing your employees' diet/allergies at work or while traveling through allergy season! The only thing about this product which can be improved would have more choices of foods tested as well - but we've found what works best so far has been enough choice without needing additional tests added later if needed by our clients who are allergic themselves too!!
