Just return if you have one. I'd give 0 stars if possible. After following all steps, the app notifies me that my test has been recalled and is therefore a useless waste of $50. Not only that, the redirect link to "apply" for a replacement test doesnt work. After Googling the correct website, Ellume makes you fill out a long form requiring proof of purchase and confirmatory results from a professional PCR test to even see if you QUALIFY for a replacement test. What a joke and a fraud.
