Charging time These units take 3-4 hours to charge up from empty and will last 60-90 minutes on a full charge. You can plug in the stones when not in use to charge between sessions. Can the Temperature be lowered? The temperature can not be lowered as it was not manufactured to be.  It was designed to heat up to become comparable to the basalt stone massage.  Therefore, it is engineered to dissipate the heat throughout the body when in use. As you use the stones the heat transfers to the body, cooling off the stone.  When comparing to a basalt stone you will notice that those stones will only cool. Sassi Stones will regenerate the heat within seconds to recoup its prime temperature setting of 130 degrees. This allows for a continuous stone massage without losing the heat or having to switch out stones throughout the massage. When used with our proper techniques as illustrated on the company website, sassistone.com, you will see that using longer, quicker strokes will help dissipate the heat, as well as using our convenient cooling pad or by simply rubbing them on yourself before using them on the client.  Once the stone touches the skin it will respond by  cooling off as it will start dispersing its heat.  As this happens you may begin massaging at any speed and the guest will enjoy the warmth throughout your entire experience.
