Product review (5 stars): Great piece of mind during a bad hurricane year.  An "actual" surge protector,not just a glorified plug
I live in rural Hawaii and our power goes out frequently, sometimes for days at a time.  To keep our food from spoiling we use a combination of generator power or I run it off a deep cycle marine battery charged with solar panels and a 2500 watt power inverter.  That opens up a lot of potential for voltage anomalies and I don't want to fry a $1200.00 refrigerator.  This surge protector is unlike any I have ever seen before.  Usually they just look like an oversized male plug on one side and female on the other.  I've always wondered if they even work.  This unit is different. I like the translucent housing so that you can see the circuit board and electronics inside.

I saw some other reviews that indicated they had problems figuring out the unit because the instructions were in Spanish.  Mine didn't come with any instructions though the label was in Spanish.  I'm not sure I understand the confusion because you plug this unit into the wall, plug the appliance into it, and then turn it on.  There is a dial on the back for adjusting down the AC voltage, that is not a feature you would need to use in the USA, just leave it set at the factory setting.

One thing I did wish I knew is what is the phatom draw of this unit.  If anybody knows I would like to know as well.

I found a coupon code for this product on the internet that got me a small discount on the price and they requested (but not required) that I would leave a review whether it was good or bad.  I'm going to buy another one at full price for my chest freezer.
