To make sure you don’t like the experience of the INNER LIGHT lamp, feel free to test several sessions at various times of the day. Preferably choose times when you are not too tired and during which you are sure not to be disturbed. If, despite several attempts, you are not satisfied with your lamp, you have a 14-day withdrawal period from the delivery date to contact us to obtain a full refund, even if you have used it. Only conditions, the lamp, the accessories (power supply, cables etc.), the carrying case and the instructions must be returned in perfect condition and in their original packaging. We cover shipping and return costs. So you can test INNER LIGHT for 14 days free of charge. To return your lamp, nothing could be simpler, contact us via the contact page of our website. You will not be asked for any justification, but if you wish to share your comments, please let us know what you did not like. We also reimburse INNER LIGHT feet and their shipping costs within a period of 14 days from the date of delivery, provided that the feet, their packaging and their notices are returned in perfect condition.
