So, I just received this in the mail the other day: https://www.thestick.com/cgi-bin/commerce.cgi?preadd=action&key=DC-3000
I finally had a chance to try it out today before training legs, and personally like it much, MUCH better than using a foam roller for lower body work. It is easier to use, being less awkward and permitting greater accuracy; particularly on the medial calves and adductors.
It seems to be well made, but it's too early to tell how well it holds/will hold up. It's also a bit pricey, but I'm not complaining.
On a less enthusiastic note, I also purchased a foot wheel in the same order. Unfortunately, the construction (at least on mine)
Within literally the first minute of use, one of the end caps came off, allowing the wheels and spacers to slide off of the core when in use. I will be contacting the company this week regarding this matter.
