Review on 🦈 Vdera SF-E-11-AMZ Sharkfin White Self-Molding Earbud: Unleash the Perfect Fit for Ultimate Comfort by Cathy Khan

I had high hopes for this thing and was completely disappointed. The instructions are almost too small to read, with tiny illustrations that are indecipherable and useless. When used with headphones, the material becomes greasy and slips when trying to get a grip in the ear. There's no way to get it to stay still long enough to get a quality print after curing. During casting, some of the material got into one of the headphones, which likely ruined it. The fabric is missing. When I was finally able to install one in my ear, I noticed that it wasn't enough to cover the area and seal after curing. I think it might work if there was at least 50% more gunk to cover the kidney and close off my ear canal, but definitely not enough to do both.
