Easy to work. Accurate results
Those were very easy to use with quick and accurate results. Great to have at home during the winter months and flu season. 3 out of 4 family members caught the flu recently. By the time we suspect the second one of us caught it, I just ordered the tests rather than returning to urgent care to find out wether we had the flu or not…

Accurate test kit
This test kit is very accurate. Used over the Christmas season when my kids were sick with Flu. Though the instructions said wait for 15 minutes, the test result will come out even before 15 minutes if its positive. Very easy to use with clear instructions and the price is reasonable. This is my second purchase. Going on a trip and I will bring this with me.

Good product… just go to YouTube for instructions
This test had good reviews so I went for it. Once you fully understand how to use it, it is easy to use and interpret results. Here are my issues with it which can all be addressed from good YouTube videos you can find…1) Instructions on the box were in a ridiculously small font. I had to take a picture with my phone and zoom the photo to read.2) in my case, I had a good outcome (eg negative for Covid, influenza A and B). You get a single result marking in the “C” row. I was thinking, what does this mean. The written instructions did not indicate how to interpret results. A generic web link is provided, but that puts you on a general page and now you have to fish around the website for the information which ultimately I could not find.I’m classically trained to read instructions but had I gone to YouTube right away, I would have avoided the headaches described. I guess companies these days rely on people doing this and don’t worry about documentation anymore.

Easy peasy testing. Easy to bring with you on a cruise.
Took this on a longer cruise. Came down with the crud being passed around. Medical center cleared me for COVID, Flu, and RSV ($350); I retested with this easy set after 6 days and was still negative. Super duper easy to take the pack with me and use.

Rapid tests
So convenient and cost effective too! You can test rapidly at home and get results in 10 minutes. Information was accurate and it’s good to have a peace of mind.

Good price point, ok test
Pretty standard combo Covid/flu test. Easy to follow instructions, easy test to administer. Knocking off one star as I did come across what appeared to be a faulty test – took about 10 minutes just for the sample fluid to even be absorbed into the strip, and then none of the lines appeared, not even the control. That said, this test functions as one would expect for this type of test, at a good price point.
