Buy a better pen - Substance Analyzer

Bad POS I ever wasted money for 3 days and it is out of calibration. Within a week the batteries died, when I attempted to remove them, they corroded and rusted in place. Of course, they only give you 1 set of buffer solution, so now I'm waiting for an extra solution that I had to buy! Buy a better pen!

Pros

Looks good

Cons

Almost never
