My friend and I used the Smart Swab three days ago. We followed the instructions and did exactly as told. He is now deaf in one ear. I have had chronic ear ache ever since. Now when I yawn, I hear a ripping noise in my ear. I was hoping the problem would go away, but three days on it has not got any better. We're both genuinely worried that this product has caused us permanent damage and are frightened. I now find myself in a position where I need to take medical advice.
Bottom Line: No, I would not recommend this to a friend
