Using this product is easy. First, get your DX Zero One Driver (if you haven't already). Then, insert the Progrise Keys from the set into the Driver Unit as needed. When you're done using it, store the keys in a dry and safe place to prevent damage. Make sure to keep them away from children who might swallow them. Also, avoid exposing the keys to extreme heat or cold. If the keys get dirty, you can gently wipe them with a soft, dry cloth. That's all you need to know to enjoy this awesome set!
