Review: Works perfectly, nice and flexible. - Works as described! Perfect for plugging in my 230v pressure washer to our 50 Amp RV receptacle .
Review: It adapted heater to wall charger perfect. - Worked as intended. Using it for a heater in my garage gym and I have an outlet for car charging, so I wanted to use the outlet since I don't have an EV. House is still intact as of writing this review.
