I purchased in total four fitness trackers from these people but two of them were not suitable, they did not fit properly ,so I endeavoured to send them back after protracted e mails I sent them back by Royal Mail with all the required info . I heard nothing for an extended period, so I contacted them again and they claimed they had never received the items. they then asked for proof of posting, which I sent them They then basically washed their hands of there responsibility I guess when you look at their website they set you up for never received scenario by saying that they are not in any way responsible in any respect for returns and the responsibility lies solely with the customer even thought I sent them proof of posting
