  1. This is a fantastic product.
    Its a good short exercise for those who work long hours behind desk.

    I used to have problem with my wrist after long hours in front of the computer.

    I think this is due to my posture or it could be my hand positioning on the desk?

    1. It also could be inherited due to peculiar wrist structure. Past traumas, fractures, tendon pulls, related medical conditions & of course your overall posture.

      Everything adds up especially on this modern era where we spend infinite hours sitting behind computer.

      Devices like this are one of many methods how we can undo the damage to some extent.
