I purchased three Hanna test kits from Dabcrusher. He said they would come with a 'fresh set of reagents' but two were expired and the third didn't have enough reagent for one test. Also, the kits were a mess. One had a dead battery, they had water in them and in the cuvettes and a number of syringe tips were broken. When I contacted him about these things via reef2reef messages he read the message that I sent but never responded. I would advise caution when dealing with him. There were a number of other times people have had a problem with him. Also, communication with him was very odd. It screamed of a scammer.
