It's pretty tricky to self-administer one of these lateral flow covid tests without reading the instructions. There's a whole sequence of steps - swabbing, mixing the swab in the buffer solution, dropping a set number of drops into the sample window. This device doesn't appear to get rid of any of that complexity - instead adding significant complexity and to the simplest part of the test - look for a line.

If you don't read the instructions then you may not work out the differences when the next set come along. In the UK we have, amongst others I'm sure, the NHS branded boxes, Flowflex, and Orient Gene. Some require swabbing nose and throat, some are just nasal swabs. Some require 2 drops onto the device, some require 4. Some require a certain amount of time to be left in the buffer solution, others just a set of steps of pushing/turning/squeezing the swab in the buffer. Some require waiting 30 minutes (minimum), some are 15 minutes (minimum) and 30 minutes maximum. etc.
