Excellent product and an invaluable and affordable addition to any kitchen. I used this product daily in my restaurant career, and am pleased to continue using such a great product at home. These test strips make great stocking stuffers for friend and family too!
There are lots of excellent products at Indigo, and the website is easy to navigate. Always great customer service and shipping.
P.S. The PH test strips and magnification items are my other favorites.

Service was excellent, accommodating my change from pickup to delivery seamlessly and quickly, offering a more economical option. Friendly knowledgeable staff. ALL THIS IN CANADA! Better than having to resort to the Amazonian Empire.

Service was fantastic, efficient and accurate. They provided me with chlorine test strips, in a quantity that suited my needs and at shipping rates appropriate for the size of the shipment. The sales rep reached out with options and assisted me when I mis-ordered. Service and support was prompt and efficient, the package arrived intact and in a timely manner. I really enjoyed that a real person reached out to support me, and that they were informed and interested in problem-solving with me. The rep listened to my needs and provided appropriate suggestions. Much more enjoyable experience, more efficient and satisfying than working with distributors like Amazon where there is no contact with a person who is interested in meeting your unique needs, no ability to problem-solve, correct mis-orders, or find ways to save money.

Great price point, customer is easily able to read the results and love that it comes in a closeable tube as our last supplier came in an envelope and we had customers having a problem with them getting wet.
