M1A2 New Generation RV Surge Protector 30 Amp 50 Amp with Waterproof Cover Camper Anti-Theft Circuit Analyzer Tester Plug with UL Tested

This works great, never know what surges you’ll get at the campground.

seems to be a pretty good product

Good product. As advertised

Item works as advertised and appears well made. It has Surge protection and is much less expensive than other overpriced similar items. It checks line connection and also provides surge protection. Would buy again.

Used a couple of times now with my generator with no problems. Very sturdy and durable

So glad we had this as we had a couple of pretty strong electrical storms while we were out. No issues - so I assume that it did its job. It is reassuring to have the lights to confirm that wiring is correct before you plug your RV in.

Good product and good price

Works just as advertised

Works as described

I got to use this product on my first weekend with my new to me camper. Best product for the ones. It comes with a lock and key, also a cover that fits over the main plus to keep it out of the rain. The best part is that the panel is very easy to read and understand. The corresponding lights and the key are on the same side. It makes checking for surges and connection information easy to see.
