Rated 3.7 out of 5 by 3 reviewers.
Rated 5.0 out of 5.0 by Dowfrost antifreeze I have used this product in our 3 pools for the past few years now. A 70,000 gallon pool, 2,000 gallon spa and 2,000 gallon baby pool. I suck out the skimmer lines and water fill lines of as much water as I can get out and pour 2-3 gallons in each and never had a problem yet and our pools are 25yrs old concrete in-ground pools. I also use it to winterize the pump baskets and out door bathrooms. I live and work in NE Pennslyvania and this product stood up to the past Polar Vortex that stayed over much of the US.

Rated 1.0 out of 5.0 by Do not recommend! The lable states that some slush may appear at approximately 0*F. I had an extra jug of this product on my patio and at 0*F it was nearly frozen solid -- way more that just some slush. I winterized my new RV with this and now I'm worried about the plumbing system in my RV. I tried to contact the manufacturer. The label has a website address which came up as "not found" on my web search. December 10, 2013
Rated 5.0 out of 5.0 by Great Product. Good price. Works as expected. Use this in my travel trailer. Have had no issues with it. Cheaper then buying from Camper Store. November 3, 2013
