If your cables is defective or broken call Ikarus at 239.690.0003. If it's just a simple solder break you can easily fix it if you don't want to wait to replace yours. Either way, they will replace it or help you fix it if that's what you want to do.

If the cable acts jittery or gets hot it can be reaplaced as well under warranty. Call 239.690.0003 and get an RMA to return it and have it replaced.

As far as losing it, sorry but they will only replace defective, not replace something that you have misplaced.
