These are very simple and easy to use. You don't even have to wear them except for 5-minute increments. Every 5 minutes charges your items up to 1,000 times. So for every 5, you increase the power. Place the bracelet on and they are all stretch. What the proper amount of time while holding you the piece you want to charge and that is it. You are all done. You can do it every day or when you feel you need it. This works on both spirited and non-spirited items.
