Heisen and Heisenbeans are thieves and GPS should find better employees than to employ people that breach their contracts with Greenpoint and lie to Gold level patrons . Do not buy testers from Heisenbeans as he will lie and steal your money. He stole 93.00 from me and was charging 89.00 for unproven testers plus 4.00 shipping. I ordered MAC testers thinking they may be something special back in June and after months of being patient he responded apologetically but never sent the order or will even repond after I kindly asked for a refund since either he does not have the order or is just a plain thief . BEWARE OF THIS PUNK! I AM A 60 YEAR OLD EXPERIENCED grower of 45 years plus a Boutique kind of guy. I was an idiot to have faith in a guy whom in reality is a glorified pollen chucker!
