I almost gave you 5 stars. The good points : You sent the test kit in time. The test kit was easy with clear instruction And the app easy to use The update about the progress after I sent back the test is very helpful ( especially that I am in the uk in in take longer until it arrive to your lab ) Why not 5* ? 1 on your website ( or app) it was written that customer are entitle to have one call to get advice about the results . I tried and asked for advice but did not receive any call or communication from you ( except the result of the test on the app) It take a long time until my "sample " is arriving back to your lab and until I can see the result . ( although I specially drove to deliver it to the Royal Mail Center on Monday at 8 am... I ordered the test twice . I realise that this iodine test ( from urine ) is testing the level of iodine in urine which can change every day according to amount of iodine I ate during the day or few days before the test . So it is not the same as iodine in blood or during the last month. However if you can give me discount I may consider to order it several times to view the level of iodine each time. Do you have any deal or open to have a deal with a healthcare company in the uk who provide health style advice and can recommend or offer your test to their customers . Best regards Tuvi
