I used them for COVID-19 testing, still have their reader, but they are expensive, device warming up takes forever, the battery drains pretty quickly, it charges slowly, and sometimes the kits just fails, and you have to throw them away, and contact them to request a replacement. The discounted price requires a monthly subscription. Meanwhile, after a few months of a pause, Lucira launched a revamped product, which is similarly priced, you don't need a reader, and it also tests for Flu type A and B.
