I backed Kerv back in 2015, they stated then they expected them to be out in April 2016. They just stopped giving updates and now all you get is estimate on dispatch from their support team. Told me 4 weeks, after 6 weeks contacted again and told another 2 weeks, after a further 3 weeks contacted again and told my Kerv ring would be posted out on monday. Yet again it failed to arrive. Received an email today from support saying they aim to send it out in 4 weeks. They really, really need to give all the backers and pr-order people waiting a full and truthful explanation about the delay. Looking at other forums and twitter it definatly looks like the new customers are getting priority over the backers. I would not hold your breath waiting for yours to arrive. Perhaps all the people still waiting on Kerv to actually supply the promised rings should get together and consult a solicitor.
