I purchased it at the 2012 New Hampshire Sheep & Wool Festival after trying it in person. I had been coveting it online, but really wanted to test drive it before dropping that much cash ... and for a wheel, its actually very inexpensive ($200-$300 less than a traditional wheel), but still an investment as hobby equipment.
Though it is not a "Traditional" wheel, it has all of the important components of a wheel. A drive wheel, treadles, a flyer and an orifice ... that's all you need to spin. It also has 3 ratios. It can be used as a single or double treadle.
I spun and spun and finished half of the roving that I had. Then I started on the second half.
I'm almost done the second half of the roving and can't wait to start plying!
