Test was great. Clear instructions, and liked getting to bang the leaves with a hammer. More expensive than I wished, as I would’ve tested more. But good quality and well thought out packaging and method.Matthew B.
Great service, great responsiveness. We have been working with LeafWorks for gender testing for several years and have great confidence in Eleanor and her team.Robinson
