Yes, I watch the occasional infomercial.
Far fewer than I did before we had cable, though.
Got one for birthday from a couple of super uncles & aunts (thanks, guys!).
It was easy to assemble, easy to use, not so easy for me to fold it up, but that could have something to do with a lack of coordination...
It does say that it does not need to be oiled, but using some WD-40 helps stop the squeaks.
Really easy to use, it is just gliding. Problems: Easy to get bored, no way to increase resistance that I can figure out, no place for me to set remote;)
Doing a mile had no perceptible impact, but legs hurt after doing 2.5 miles. Then again, I am a wimp.
It's a nice, easy way to get off your keister & feel like you have done something mildly athletic.
