So much this! In my case though I suffer from fine-motor control impairment since childhood, making normal drop-counting titration tests unbearably painful to perform.Thanks for the review. Hopefully it gets straightened out. Digital testers may seem like a toy to a lot of reefers but they’re a quite a few of us out there that can’t perform titration tests with our eyes so these really become a necessity. I’ve been holding off getting one until more reviews come in. Man, if you think that’s inconsistent try having non-reefers try and perform titration tests for you….ha
