Does anyone live near or in Cardiff who could hep me?

Hey everyone. I have finally done it! I have designed a arthritis friendly childproof bottle cap. I have already tested it with one arthritis sufferer however to make sure it works i could really do with some more feedback. I was wondering if anyone could help me with this? If anyone lives within travelling distance of Cardiff and could help me. I would greatly appreciate any feedback you could give. I have also tested to make sure that children cannot open this cap and so far no children have been able to open it.
