Faulty $19 charger-Worth returning it to HKE?

Recently bought a faulty Xtar WP2 ii from HKequipment, cost $18.99. They've offered an exchange if I return it but shipping + hassle seems hardly worth it. Also, I'd have to write their address in English, so would it even reach them? What's your opinion?

That's what you will have to do, try and get them to pay for the shipping back.
