Dynaflex Dynagrip Stress Grip Ball GP210 (Colors May Vary)

Es un producto bastante bueno, sin embargo es un globo relleno de harina, es decir no representa un producto "único".En general si funciona para el manejo del estrés, pero no es la caja, sino un globo nada mas.

good size

I have a couple other grip strengtheners and there's not a single favorite as they all serve different functions but what I like about this one is that the hefty feel can replicate a guitar neck so you can really let your inner-air-guitarist out. Not a bad price but I'll try to make my own with sand and balloons next time. This one has two layers of rubber but they're very thin. If my DIY doesn't work I'll definitely come back and order another one!

Recovering from carpal tunnel surgery trying to get the strength back in my hand and I like another stress ball I got awhile ago that's the dame latex material but filled with cornstarch and softer easier to manipulate a couples weeks after surgery but then I graduated to this one and it's firmer more like sand is in it, it's a good building block for building strength back up

Bought this for our sensory-seeking sons. They like squeezing and squishing it. It's good for helping them to 'calm down' when upset -keeps them from pinching people (ouch).
