### ⭐⭐⭐⭐⭐ My gas motorhome has new radiator and just gets too ...
*by P***R on November 9, 2017*

My gas motorhome has new radiator and just gets too hot on long hard pulls connected the heater hoses to it and motorhome does not get hot now it only has air flow going through it while driving. Solved my over heating problem.

### ⭐⭐ 1in outlet/inlet not round
*by R***R on November 4, 2020*

Not impressed. I felt measurements were a little misleading, that could have been my fault. A pic with dimension on it would clear this up. One of the 1in ends was not round. After 30min of sanding, trying multiple copper fittings I finally got my calipers out and it was out of round the whole time.

### ⭐ Maybe try a different brand?
*by J***S on October 24, 2021*

Didn’t last a year is leaking in to my basement. The outside mana fold part failed. So I guess I try a different brand hopefully fits the same hole I got for this one. These are fairly easy to install and shark bites fit right on them with no soldering I honestly thought that would be my problem but that part actually held up.
