I am looking at both but the Fast Coolers are $125 vs. $239.95 for the Trans-Coolers. Anyone one using these. I would appreciate hearing about how both of these work, your likes and dislikes, and recommendations. Thanks!

I have the FAST Coolers on my truck. I put them on before the Trans cool was on the market. There are pro's to both.I like the additional capacity of the FAST coolers, as well as the price. The Trans cool does appear that it would cool better. I have never ran a temp gauge, but all the posts I have read on the FAST coolers shows a decent drop in temp. The drop in temp I have read about doesn't warrant, IMHO, the additional cooling of the Trans cool's. Give the choice today I would stick with the FAST coolers.
