I have be look for adjustable weight and they be either cheaply make or way too expensive . I think these be a good balance between price and functionality . there be no way I be spend $ 400 on the Bowflex one , and when I try the Reebok one at target , they be tre cheap -lrb- not sturdy enough -rrb- ! it be a little fidgety to get use to how they work , but it only take a few try to get it down . I like the color coding of the weight increment , make it easier when you be try to shift from one exercise to the next . I use they with a series of video -lrb- Chalean Extreme -rrb- which be constantly change weight between exercise , and I find they very manageable . also , I like how compact they be to store and to use . the Bowflex one look so ungainly when you be use lower weight . I think this be a great product , and I highly recommend it !!
