Great product but the one I recieved was definitely used. Missing one reagent wet wrinkled instructions. This was sold as new beware of purchasing from amazon maybe get this directly from the manufacturer.

Does what it says with great accuracy. I have been using it for about 4 months and would totally buy it again.
