Excellent value and great service thanks Rock and Run
Great, easy to use
Not used yet, definitely worth a buy in the sale. Got the green ones, bit of a mark on one of them, yet to try get it off - may be left behind from a price sticker? Also, yet to use them so can't comment much on that, but I can say that they look decent, feel good & came very promptly.
Compared to the static feel of fingerboarding these rock rings feel distinctly odd as they can swing around, no doubt the extra movement will help develop better body tension and muscle tone (both areas of particular weakness for me)
