It wasn't the best experience. First, off the prepaid label, I had to print and use was not valid at the post office and I had to pay for postage myself. Around £7.50. I suggest you look into that and change the postage method for others who use your service. In addition, I was quoted £199 for my device which went down to £60. Again, the jump down was so extreme. I only went ahead with the sale because the hassle of sending it back would have been not worth it. My daughter's old phone was still working and she was using it prior to her getting a new phone I won't use the company again for selling a device.
