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.

I was told by another RV person that if I put the adapter on and plug this in to 50 amp I have a fear of ruining it. I usually plug in the 30s but if the 50 opportunity was the only outlet available somewhere, I wish I had bought a 50 amp

Inexpensive insurance— you never know what kind of power you are going to end up w/at some campgrounds. I would rather blow a $60 part then all of my control boards in my camper.

It works well serves the purpose. I could not close the plastic cover because of the handle at the end of my cord and mine did not come with a lock/key and lanyard as advertised, am not sure why.

Works as advertised, high quality, recommend this product to all rv users.

Great price. So far so good!

This is a great product! Works well and I now feel that my RV electrical system is protected! I would recommend this surge protector for anyone with an RV!

Works as described

Like the lights giving the ok of connection. Found out that my 30 amp home connection plug was wired incorrectly. Got it fixed.

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.
