Home sperm test kits

​Has anyone tried the home sperm testing kits? My partner tried one but it gave a negative result which meant he had low or no sperm count. A few hours later the test changed to showing positive, it does say to ignore any result showing after the 7 min test period but I can't help but hope it just took a bit longer to get result. Would love to hear if anyone has tried these and got same results but went on to get their BFP.
