How long does each Primer last?

Your Primers act like sponges - they absorb water to help make good contact with your scalp.  Over many uses, this ability to absorb water may decrease, which makes it harder to get good contact.  If you notice this happening, use the Recharge Pack to restore the ability to absorb water quickly.  In normal cases, this won't be necessary until after many sessions.  If you clean the Primers vigorously, then you may need to use a Recharge Pack sooner. Watch this video to learn how to recharge your Primers. 

Primers are designed to be long-lasting and repeatedly rechargeable using Halo Recharge Packs. However, like your running shoes or the padding in your bike helmet, Primers can become physically worn out after extended use. At this time you can replace the Primers.
