Do you provide a warranty for CoolWallet S? What can I do if it stops working?

The warranty is for 12 months. You should have a back-up for your Crypto. If CoolWallet S is not working within 12 months of normal use, please contact us and send your CoolWallet S back to us. We will send you a new CoolWallet S within 2 weeks (subject to spare cards stock availability) from receiving your CoolWallet S.
