If you're wanting to get vendor refund/replacement protection, yes. Me personally I could care less about that. Jano already costing me $300+ for the testing, shipping and the straight up hassle of sending overseas. Kind of silly for a kit that costs less than the test. At this point in life I'd rather just buy a kit and wait to see if reports start popping up that it's bunk, or sacrifice a vial to Finnrick for a couple bucks shipping, and if it's bunk take the $300 Jano fee saved and just buy a another kit elsewhere.
