I ordered this and the regent powder is clumpy. Has anyone run into this problem? I'm concerned the test reading can be inaccurate because of this.

My recent order was also clumpy and brownish in color. My reading does not appear accurate. Has anyone else verified?

Consistent and Well Packaged

These reagents do what they’re meant to do. They’re simple to use with the HI 782 checker and the readings have been consistent and accurate for me. The packets are well sealed and easy to open. You only get 25 tests, so last well for what you pay, so they’re not the cheapest per test, but Hannah reliability isn’t questionable.
