Review on Comimark MT8870 Decoder Telephone Decoding by John Castle
4 out of 4 points didn't work!
All four 8870 DTMF boards were dirty and showed signs of corrosion at the solder joints and improper cleaning, did not work when switched on. The low price means you get what you pay for. I want my money back or four devices that have been tested to work properly.
