Title: Dynaflex - wrist exerciser
Review: This is a great toy/tool for exercising your wrist and forearm. It is also meditative and fun. The down sides are that1. It is noisy.2. The learning curve is steep, and it can be hard to learn to start without the string, (included). Starting with your thumb requires a very fast flick, and a good feel for the rotation to wind it up to speed from a low RPM.Videos of others starting the Dynaflex are mostly unhelpful or else they are advertisements, so the beginner is mostly on his/her own with the learning curve, and that may be best anyhow.
