wrong product

These are much better than the tablets for checking chlorine levels at work awesome buy

Quick, Fast, and effective service. I needed these as my water DP Tabs were out dated, and i needed a bunch of packets for operations and maintenance of a water system. Made it in great time and was able to get proper readings as the old packets were out dated. So i am happy to have recieved these in the knick of time. I passed my site water safety in a timely manner.

Product as advertised. Fast shipping
