Tread climbers, anyone use them?

[TheVTCGuy]

So, about six months ago I got very serious about my physical activity and excercise routine. Oh, nothing hard-core, just walking for an hour every day and a visit to the gym for some weight-training every other day. I feel better then I have in years and have lost about 18 pounds. I plan on continuing this but have an oppurtunity to get a free Bow Flex 3000 tread climber. Long story, but a good friend of mine bought it a couple years ago, never took it out of the box and owed me a couple favors so offered it as a (very nice) gift. Right now, I will typically go to my local gym, ( a very nice one with the latest equipment) and walk on the treadmill while I watch TV. I figure I'd be sitting on my fat A%S at home watching it, I mine as well burn some calories and get a long walk in while I'm doing it. The treadmills are very nice, big TV screens on every one, I channel flip just like when I'm sitting in the lounge chair at home. Anyway, getting back to the treadclimber.

If I accept his gracious gift, I could put it in my living room, and instead of going to the gym to walk on the treadmill at night for an hour while watching TV, I can do the same thing in the comfort of my own living room and own TV. Only thing is, I have never used one of those tread climbers before. I hear they're pretty good.... does anyone use one? I don't want to take it from him if I use it once and then leave it in a closet for 59 years.... But the idea of not having to actually GO anywhere to "walk and watch" is pretty appealing.

Anyone?
