It's on 24/7 and so far no issues. I agree 100% with it being a no-brainer, especially where there aren't other options. Dialup was KILLING me! As far as using it on the road, I've done that a couple of times and it worked fine along major interstates. There are some areas though where the signal dropped to dialup speeds or disappeared altogether. Of course, YMMV, but all in all is well worth the $$ in my opinion.
