You'll never go back to your old strips
I won't go back to basic test strips again. These are quick and easy for pool water monitoring and the results align well with other more complicated tests I've done.

No lot number. Not traceable.
I like the small size and it was well sealed. It didn't have a lot number, no expiration date and no documentation for traceability.
