Came on time. Package well, no complaints. Although, the test pack doesn't seem to be a true litmus test from what I can tell thus far. If something changes I'll post again if there's a question.

Works as it should

Came pretty quickly and was amazed of how many strip tests are in those two boxes….works good for quick ph tests, not for decimals though! Would need a smaller range like 0-7 to get a more accurate ph,but good enough for household use!
