Works effectively but not on some iPhones
I bought this some years ago but having seen the negative reviews thought I’d comment. The product worked straight out of the box when I bought it 3 years ago, on my old iPhone, but this time I had the same problem that has been mentioned about “no wifi connection”. So I tried it on an old iPad and it worked immediately. Must be an incompatibility issue with later hardware. Be interesting to see if the developer acknowledges this.
