It's a good quality plug, and is perfect for my brother's car charger. The reason it doesn't get five stars is the box is a little cramped to install the wiring, making it a pain to put together.

I used this plug in a simple RV inverter installation. Rather than installing a transfer switch on my first trailer, I simply wired this weatherproof plug to the inverter outlet and mounted it to the trailer frame below the inverter compartment. When shore power wasn't available, I simply powered up the inverter, which fed this plug, connected the RV power chord to this plug at one end, and to the RV power input at the other, and had full 120v to the entire RV. Far simpler than installing transfer switches, if you don't mind walking outside and connecting some chords, like you would with shore power anyway. This plug is high quality, well constructed, and still fully weatherproof after 2 years of RV use. Recommend both this item and seller based on my experience.

It is a PVC ( I think ) box. It has a good solid feel to it and feels well made, It also has a good fit with my RV plug.I would definitely recommend this to anyone who is looking for one of these boxes.

Love this Outlet box and outlet. We installed in a garage to use a portable Tesla Charger with. It is safe for little hands and looks great next to the garage door on the wall, tied into it with flex conduit. Works!

I installed it in my garage for charging a Tesla Model 3; so far it works very well ... it looks great and I cannot feel any heat as I expect. Satisfied with the performance and appearance of the product.Two tricky issues:1. The wire openings do not fit US standard connectors ... the threads are thinner for US connectors. I use a 3/4" connector for the 1" opening instead of one of the two 3/4" openings on the box. Another option is to drill a 3/4" opening on a side of the box for the connector.2. The box needs to be installed on the wall ... need a few screws and drill some holes on back of the box. No instruction nor hardware is provided.The installation instruction is useless. One would think a company invested into developing and manufacturing a solid product should spend 30 minutes to write a useful instruction.

Be aware that the fittings are metric, and it is deceptively small.It's wonderfully made, the design is fantastic.
