I sent 3 mobile phones to 3 different companies to sell and Gecko were easily the worst by some distance. They were the only company who I asked to send my device back to me, so poor was their offer. They initially offered me £48 for my I-phone SE so I sent it to them. They wrote back to advise me that there were "Too many scuffs and scratches across the device to qualify for "Good" Grade" - absolute nonsense and completely unfounded. I have photos of the front and back of my device to prove this is garbage. Their revised offer to me? £12 - A 75% REDUCTION! This is despite their FAQs reassuring people that they would only reduce the price "slightly" if a problem was found with the phone. Haha, what an absolute load of rubbish. I rejected their offer so they returned the phone to me I received the phone back today and not only did they NOT send back the original box which I sent it in, they left a stupid bar-code sticker on the back which took ages to remove. What an atrocious service to leave that on there for me to remove. There are a lot of good mobile recyclers out there - I would 100% NOT recommend sending your phone to Gecko based on my experience.
