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

Great work, All plants were 100% correct!
The kit came in the mail within a few days and got back to them a couple days later. They tested it immediately. Great job!
Terrible. Nobody ever sent me any results.
