I ordered this kit on Monday and it arrived on Wednesday. There were lots of steps to follow in the instructions and my husband and I both read through to make sure we knew what we were doing, but each step was simple, just not a task to be rushed. I think the kit was easier to use with someone else to help apply the blood to the test card and I would have found it awkward (but not impossible) on my own. We used the two tests in the kit to test my husband's blood type and we also tested mine (which I already knew) which gave the correct result. This reassured me that my husband's would be correct too.
