  • "Good value" by don on 8/19/2014

    I really like this module. The new "N" version does share a common ground between the input and output. This is a very good improvement over the earlier versions that did not. For the price, it is a great value.

  • "Not bad but not great" by Barry8Tracks on 2/26/2014
    Overall: 3 out of 5

    Quality:

    I'm not too crazy about these modules, especially the fact that the input, output and power don't share a common ground. Despite the specs, they sound closer to 5 watts than 18 and don't do well at all using more than one speaker. I went with another MCM product with much better results.
