Been running on the first batteries for about 3 weeks so far. I am very happy with the even temperature within the frig.
Bought it for the RV fridge due to the 105 degree Texas heat. Put 2 bottles of frozen water on each side of it and it does great. Back down to 32
This is great since it moves the cool air evenly thru the frig
I could tell the difference the first day I used it. The fridge is much colder now that we have cool air moving through out the fridge. Well worth the money , the best part is it's made in the USA.
