Works just as good as the others

Works well / does what its designed to do with a higher water to antifreeze ratio and is very cost effective at the pricing point in comparison to other retailers selling it $10 and higher. Its also is cheaper than other brands that do the same which retail $14 or more. Ive only used one other higher priced brand and that is Redline Water Wetter and I haven't seen a difference in my using / vehicles. It wasn't in stock ( though it says it is ) at my local Walmart but it was shipped to me because it couldn't be found on the shelf.
