I have used this plugged into my dryer outlet with an adapter, and recently had it hardwired. Worked great both ways. The screen interface on the unit works fine, but I wish you could turn off the password completely. I like the options of RFID, password, and app configuration. I use the Smart Life app with other devices in my home, so I was glad to see it works with these chargers. The history doesn't always show up properly in the app, though, and there's no way to show charging cost figures. The gasket seal appears solid, though mine is inside my garage. The cable is hefty, thick gauge as needed for the rating up to 48 amps, even my electrician noted the cable quality. I checked myself and did find it on the ETL UL registry. I'm very happy with it, this is my fifth Vevor product, too!
