I’m a gadget guy, have used a controller since the beginning... I don’t think I’ll use the trident untill it has been vetted for a few years by other people.
I was lucky enough to get accepted to the NSI team later in the beta testing. I love it so far. It's been very precise and has maintained the approx. same variance compared to my salifert test kits. Multiple Trident tests performed manually within a short time period have been within .05 dkh approx.
