I was apprehensive given the largely negative reviews and feared I may not get my passenger locator form code to travel, and that this provider may be just another one of those providers who've failed to deliver/respond - you'll know what I'm talking about if you've tried frantically searching for test providers only to realize all of them are bad. So, I reached out to a couple of providers to see if any actually cared to respond timely. I decided to take a chance with Confirm Testing as they responded spontaneously, had lines that were manned, and were very helpful along the way. They were kind to make quick arrangements to ensure my kit was delivered before my arrival (and I had the flexibility of changing the courier date), and writing back to ask if I may have any further concerns. My test result came through just two days after I had posted out my sample! I'm absolutely pleased with the service rendered and would use them again for my travels. I know the page is loaded with negative reviews, but I'd still highly recommend trying them.
