Review on ⚡ Heunwa Power Save Box, 90V-250V 30KW Energy Saving Device, Electricity Saver for Household, Office, Market, Factory (US Plug) by Brian Cheney

Here in California, our utility bills are constantly rising. I figured it might help keep costs down by saving electricity. Well I have several years of energy bill records and have been using them since mid-November 2019. My records show no savings as my electricity bills have remained almost the same as several years of records show. I cannot recommend them as they simply do not do the job as advertised. It's not even worth sending her back to Revane for me.
