Cost $60. I figured it would be cheap if I could block unwanted calls. I managed to accidentally block two unwanted callers and my own phone. This article just didn't do what it was supposed to do. The instructions are in English. The grammar and sentence form was bad so it was probably translated from another language. Maybe something got lost in translation. I had really high hopes, but it just didn't work out. It's also the second "call blocker" I've bought. The first is from another company. It couldn't have been better.
