Not worth the money, avoid

When I tried this decoder, I found that it was a complete waste of money .The instructions were unclear and there was no support available. The only positive aspect was that it was easy to install. However, it didn't work properly and was incompatible with my current computer setup. Overall, I would not recommend this product to anyone in the computer industry. Save your money and invest in a more reliable decoder..

Pros
  • Accurately decodes telephone dial tones.
Cons
  • Requires proper electrical connections for reliable operation.

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.

Pros
  • Single board computer
Cons
  • No automation
