I spent enough to get free shipping. These people were very nice and provided guidance to obtain their products. Made my life easier and that is all I care about.

I have always been satisfied with Hanna's products and customer service.

Works accurately with great precision.

Hanna did great just as always! I have been ordering directly through Hanna for 8+ years now and I couldn't imagine doing it differently.

Customer service is excellent, fast shipping and a great tool to have.
