So far I love everything about this device. It is a bit hefty. But I suspect it is engineered for performance vs.compactness. The app is nice in that I can get an idea how much current any appliance draws when it turns on. I like the bright light because it illuminates the utility side of my trailer if I need to get to something after sundown. If it ever becomes obtrusive, I will just hang a black trash bag over the power box. A 10 dollar cable lock from wallys mart seems to solve any potential theft problem. But you could also put a small padlock on the hasp that seems to be on every power box. (the plug is actually engineered so that you can fully close the door) i will change my tune if it smokes in the next year. But so far it is the best $xx.xx I’ve thrown at my rv.

I ordered the Power Watchdog at 1019 hours on 7/24/21 from etrailer and they shipped it the same day and I was able to track the package via tracking information which I also received from etrailer awesome service. I received the package quickly and in great condition. The price was also very competitive. What's not to like. I will order more items from etrailer in the future.

Hooked up my watchdog surge protector with blue tooth today. followed directions supplied and blue tooth connection was a snap. was able to tell current draw for each of the appliances in my camper which makes power management much easier. Like the display with voltage, amps and kilowatts used which is resettable. What really sold me was the blue tooth to my phone so you don't have to buy a separate remote meter. Blue tooth on my iPhone was good for over 50 feet. After I ran it off my house power I tested it on my inverter generator. Made a floating ground plug for my generator and everything worked great. Looking forward to camping without the worry of guessing about power quality where I hook up.

etrailer good product good price. I knocked off one star because the dog face light is way too bright and apparently can't be adjusted or turned off(might be better if it just came on with a problem?). i appreciate the idea of an indicator light but it certainly doesn't need to advertise or light up the campsite as well as indicate status, especially with the potential for theft. As to function it seems to work... it did for the few tests i ran and the bluetooth app/connection (though minimal in it's info) worked well, was an easy setup and much appreciated.

- HU67FR

This thing is MASSIVE! It is the big dog on the block or the campsite! It works great and protects all the fragile components they put in campers today. I would much rather replace a 200$ surge protector then replace the 200-400$ Or more circuit boards on the AC unit the fridge, or other electronics that are installed in my camper.

- HU67FR

Works right out of the box as described. App is easy to set up and sync. App works as described and is easy to use. It's nice that the surge board can be replaced for $xx.xx after a few surges instead of having to buy a new protector. I don't particularly care for the bright light of the dog face. It's not terrible, but I'd like to turn it off if I could. I also would have liked to have seen some weather protection over the female plug.

Just received watchdog yesterday,so far it is working like a charm. Very satisfied with item.also I will be ordering an extra surge protector just for an extra back up since am a full time rv'r.

- HU67FR

First trip using Watchdog. Appears to be working as advertised. Very easy setup. Love the smartphone compatibility.

- HU67FR

Easy set up, I Just plugged it in and connected my RV.. downloaded the watchdog app, scanned the barcode on front, activated the app. It began taking readings immediately, right after the 30 seconds or so to "POP" and turn on and the Dog face lights up white.! I Got a quick E7 ground code after I moved the unit, the Dog face turned RED! and I found I need to replace a bad cable that i can see is a little burnt inside on the ground connector. The Watchdog reset itself in 90 seconds and all is well. So far So Good!

- HU67FR

This thing is awesome! Watch what happens when your AC kicks on, add in the microwave, now the water heater...the app shows watts, volts, and amps as well as kWh. Great for determining how large a generator you should be using as well. Love it!

- HU67FR

Quality made product! Exceptional service from e-trailer. I "hope" this will last for years to come. By the looks of it and other people's reviews, I would say yes! Buy this with confidence and especially from e-trailer. The company is so easy to work with!
