It was very fast.

Great quality for my hanna checkers

Fast turnaround time from placing the order to shipping and receiving it. Clear communication if/when something is on back order. I have called customer service after looking on the website for the number to speak to someone. The person I spoke with is knowledgeable and very polite/professional. All around good service.

Using Hanna’s products for water testing has been the standard for many years.

Good quality, fast shipping
