I used it a total of 10 nights/days over a few weeks (4 of those with on/off afternoon thunderstorms - so in dry weather and in the rain), and it worked as described
Great price and value considering the consequences of not having one to protect your R V.
Surge guard works as described, had a power surge first night out and the surge guard worked great
Besides this, after reading different reviews around the web, I noticed that many folks stated that units such as this (not only this brand) are really only good for one good power surge, which would fry the unit and then need to be replaced
On top of this, these portable surge protector seem to have a reputation for coming up missing at campgrounds
Great price and value considering the consequences of not having one to protect your R V.
Surge free and happy!We have spotty power often and this unit keeps our campers electronics safe!
