I just didn't like the ball joint/swivel on the Nano tube.

The only difference between the two hoses is the ball joint on the Nano hose. For some reason, for me, there were more leaks using the Nano hose.

It was the ball joint swivel that bothered me. With it I had leaks. Fewer leaks with the FX hose.

Tried the Nano, standard, again the last couple of nights. I used the tube from my FX pillow instead of the tube that came with the Nano. For me that seemed to work the best. The Nano certainly is comfortable.

Thanks. I rec'd a standard for trial purposes. I'd like to try a wide to see if it fits better.

Anybody know if the Nano comes in different sizes ?
