Input:
Looking around at reviews, the biggest complaints are those devices that don't feel sturdy, are wobbly, or the wheel is not thick enough to provide support.  This product is worth the price if you want one that is well made.  Wheel is plenty wide, bar is very sturdy, action is smooth.  If you are looking for a long-term investment, paying for this one is worth it over the cheaper models.  Only comment was that it did not come with any kind of instruction booklet.  However, one was not promised and it is probably assumed that those who buy this item know what they are doing.
