I just looked at the website. It weighs 6.5 kgs, or about 15 lbs, and will run for 2 hours or 2 miles. It actually looks like an interesting product. I don't really need one for checked luggage, but I'd love one that was carry-on sized -- I do get tired of lugging my roll-a-board around airports. Unfortunately, both the soft-sided and hard-sided versions look a little too big for carry-on.
