I’ve been using these for about three months with no issue. Plus, you can turn them off and on remotely through the app.

Note: I’m running two power supplies at ~910 watts on one of these. It’s rated to handle up to 15 amps and also has multiple protections built-in. You can even set a custom max limit so the unit shuts off when exceeding that limit. As far as accuracy, I’ve found it to be very accurate.
