I've used the cheaper version and I can tell you that this is well made and sturdy and it allows you to work your abs, shoulders, back a lot easier than other methods!.
It's robust and sturdy yet light weight and easy to bring along with you to the gym, on the road or wherever you happen to want to use it. Works great on my carpet without cinching the fibers or slipping. It also works well on hardwood floor, but beware if your floor surface is slippery. The wheel is lined with a rubbery tread but it won't save you from slipping on very slick surfaces. This is definitely a great value and much higher quality than I expected!. No doubt about it, this looks easier on television! I've added this to my travel bag of ad hoc workout supplies.
i would buy them again. i have had these for almost 10 months. these are nice. i swim 4 to 5 times a week in a chlorinated pool and these are holding up great.
I normally swim three times per week for about 1. 5miles each time. I was getting a little sad that my lycra shorts did not last more than maybe 4-6 months before becoming too risky to wear in public. Very happy with this shorts, the fabric is not as smooth as lycra, but it's been holding it's shape really well.
Ordered one size up and it fits fine. I'm a 34 in jeans and pant sizes and the 36 Aikiki fit is just right.
