Works as Advertised
There was a bit of a mix-up with the information on the Hanna site. This is a clear vial and a vial of something with iron in it. You have to add a packet of reagent. This worked well enough for me, but I was concerned about having to buy a new test kit every time to verify my Checker's reading. After mixing the reagent, the vial seemed to keep the color and read correctly for at least the past week. I don't know how long it will last, but it is longer than I expected, so far.

Hanna Iron Checker HC? colorimeter calibration standards, 0.00 and 1.00 ppm 
Overall greood experience. I'd say 5/5 on all counts, except the website has its quirks. The item I purchased was not in stock and the mailing address I provided was not useable, but the website allowed me go through with the transaction, even with emailed invoice etc. But the AquaCave staff is on top of things... they personally reached out with an email to tell me my item was actually backordered by two weeks and that I'd need to ship to another address. They promptly cancelled the first order before my card was even charged and I placed a fresh order. They also answered the phone when I had a question and were very responsive and helpful. After all that it was super smooth sailing. The item shipped faster than expected, was packed immaculately (rare in this day and age) and I got exactly what I paid for.
