Ordered this on 3 December - Mikes's Dive Store did not appear in Royal Mail System until 12 December and on 16 December still not turned up, will be over two weeks late by the time it turns up, if it ever does. Have tried repeatedly to get Mike's Dive Store to refund the item as will now be too late for my trip. They are not doing so as stating that have to wait for item to turn up, then to send back and only then will they refund. Have asked them to cancel the delivery but they won't. All very poor user experience and will not order from Mike's Dive Store again.
