I used the No-Kink from Camping World for about a year and a half. It worked well - till we did a winter trip thru AZ last Jan. Temps were down in the teens and I had a problem with the plastic end cracking when I attached it the water. (no - I did not leave it attached - only long enough to fill the water tank..).
But here is the happy news - the MFG offers a lifetime warranty. This is also not one of those warrantys where you send it back to them. I just took it back to Camp World and they gave me a new hose.
Can't beat that!
