Avoid, avoid, avoid. The day they are government approved but that means nothing at all. Ordered and received day 2 test but no link to register the test. I fly in a few hours back to the UK and after around 20 email requests I STILL haven’t received the ‘separate email with the link to register’ the test meaning I cannot complete my passenger locator form to renter the UK. No customer service at all. Just an auto response email which does not contain the relevant link. No phone number. I have requested they call me about 10 times but no response. If I get stuck at UK border patrol, having pre ordered all the relevant tests I will be taking Dante Labs to court for any expenses incurred. DO NOT USE THIS COMPANY
