Great customer service, arrived quickly, just as described, easy to read.
Perfect to balance H2O2 in hot tub.

I really appreciate the great services provided by Indigo Instruments. My order was shipped in a timely manner and my customer was very happy to receive the test strips.
Smooth transaction all the way around!
Definitely recommend this company.
Easy online ordering. Was ready for pick up in no time. Have always used these test strips from Indigo for testing my hot tub. They work great and are reasonably priced.
Product works good, price seems reasonable.
However, they didn't do what they said they would do for shipping. The site said orders before 11am shipped same day. My order was after 11am but, i felt it should be shipped next day which did not happen. It was handled as an order that came in after 11am the next day & then there was one more extra day delay for 'power outage'...disappointing!

Very fast shipping, good order accuracy. The test strips are a cost effective way to accurately manage residual H2O2 levels.
