This is a good solution for powering up a Shruthi Mutable. I actually have three myVolts Ripcord 9V DC, all on an *IKEA* outlet, and everything works fine.
The construction seems serious, the textile thread is a plus for protection.
Note: The little lace is nice for tying the wire, but you can easily pull it out because the metal piece is a screw, so you can plug multiple Ripcords together.
