The materials were well packaged and the instructions clear. They arrived quickly. But the uploading of video of the test was a nightmare on the app and the website. The app slightly better than the website. When it wrongly rejected a video for wrong technique. As a result had to use another test. Once results were eventually successfully uploaded the certificate came very quickly And the tests we ordered for the Day 2 testing arrived without the correct codes. We did not know this until filling in the PLF abroad. As a result a last minute panic to order new tests from a different supplier in order to get the right codes. Waste of time, money and energy Overall a mixture of quite good and really bad. Can’t recommend
