Good product. Useful for baking sourdough bread.

Item was backordered when I purchased it, but I had to find out via email. Would be nice to be let know upfront if something is on backorder.

Your review would be a lot better if you had those lightweight testers in both pH testers for freshwater nitrate tester for freshwater and so on as you offer for salt water, you should offer for freshwater

Shipping was fine. I contacted customer service with a question, and they responded the very next day. Overall happy with the company.
