Really great experience, I was wary at first at sending my headphones away via post instead of taking them into a shop but … read more I highly recommend this service. My headphones were tracked the whole time, I had access to a portal where they took photos of my headphones when they arrived so I could see they arrived in good condition. They updated me regularly on the progress and the cost was exactly the same as the quote. I am very happy with my experience. -
