BeerGoggle:
I have been running that one you ordered (black tube, blue cap) for a couple months with no problems. I had to ditch the stock tube as it was catching on my DC/USB mount and pulling out- plus it annoyed me in general.
I thought about cutting a cm or two off, but decided to wait and see if it loosens/stretches up over time and cut it then. So far, it's held tight.
I just pushed it on, but I'm wondering if I shouldn't add an adhesive? Whatcha think?
