Using it for my motorhome to plug in the 30 amp box in the driveway. I had just installed the box and was happy to see it works as it should. The box is waterproof but this adds another layer of water resistance and I can see at a glance if the power is working correctly. Plus it has a locking feature that may be useful.

It works for our 30amp RV.

This item works as expected!

After experiencing a tragic surge event that blew out electronics due to a lightning strike, I put surge protection on everything I own. This includes installing a whole-house surge protector on my electrical panel and also using quality brand surge protector for my electronics. This RV 30-Amp protector is a perfect way to not be a victim to the immense campground power grid. You’re camper electronics won’t be attacked by a neighbor camp’s crappy camper shorting out and creating a spike or a lightning strike — as the old saying goes, if it isn’t storming’ thh my run you aren’t campin. Like some of the other similar units offer, this has a weather protector shield that my cord plug fits perfectly into. The LED indicator lights are great to see the campground grid is safe to use.

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.

The unit itself appears to be working fine although no real way to know. The little cable lock is a joke. I cut the cable with an electrical wire cutter. No big deal as I would not use it anyway.

Theres not much to say it seems to be working. Havent had any issues with it yet.

Easy to work with. Well built. See how long they last

I like that it was easy to read and know that I was good to power up my coach. I didn’t appreciate the lock though. When it was time to shut down it took many attempts to get it to unlock. So many so that I almost cut the lock off.

I that the price was good, especially if it works like it’s supposed to and saves my camper in a storm. Camps not open yet so I haven’t had a chance to use it yet.
