I was plugged in and a wire came loose… I was plugged in and a wire came loose on their wiring, park and hot touched ground. My magic power box protected my coach, no loss of anything but an inexpensive replacement part that took all of fivr minutes to replace. So add up the cost of a new converter, tv, dish box, refrigerator, heater, etc etc, and you would be silly not to have one of theses for your coach.

I purchased this unit 2 years ago and… I purchased this unit 2 years ago and it was in use a total of 10 months ,it is completely dead now ,not sure that it really made any kind of a difference to my RV ‘s electrical performance at all,

Not knowing exactly how this thing… Not knowing exactly how this thing works, I still have a level of comfort knowing that its doing its job. The issues I've had are with the ground connection and the neutral connection. At my house, I have a 50 amp hookup. These regularly illuminate red when I first hookup. Hours later I'll check, and theyll be green. Dont know what to think about that. I like the weight of the device but I'd like it to be a little more weather proof as mine is starting to show sun fade and maybe even a little rusty in places.

Tired of low voltage or power spikes, try this I got tired of low voltage damage to my RV components. The last time I replaced the refrigerator circuit board, I got the Hughes 30a autoformer. I haven't had a surge or low voltage problem since. It works flawlessly without constant monitoring. THANKS HUGHES!

I have your 50 amp Watch Dog Surge Protector Thank God I have your 50 amp Watch Dog Surge protector I always questioned why I needed it. I was on holidays on Manitolin Island at a camp ground 30 Amp hookup. My power kept cutting out checked my watch dog app at a total of 10 amp consumption my voltage was dropping to 104 Volts and tripping out. Thank God I didn't need air conditioning at the time I probably would have burned it out. Great product I would highly recommend it.
