Hi Andrew, thank you for your feedback. It is definitely worth sticking with the Mattress Cover Kit. Earthing is quite an individual experience; for some the effects can be immediate and dramatic and for many it can be a much more subtle experience and can take a while to feel the full benefits. With this in mind we offer our 90 Day Earthing Money Back Guarantee so that customers have ample time to really give earthing a good go. If, as you approach the end of the 90 Day period you don't feel that the Earthing product is right for you, you can return it to us for a refund. We have emailed you some further information about this. With best wishes from Earthing Oz
