Hi JHB, thanks for the feedback. I'll certainly try to incorporate including a phone number onto the site. :) I was a bit hesitant of including it for spam reasons but I'll try to incoporate it now that you've mentioned it.
I'm pretty sure they are genuine but when buying from them you always run the risk of getting caught by customs and then having to pay VAT + customs duty which may put the price above £50 per rubber!
Thanks for the help - Just to let you know I think I am going to be able to provide a 15% saving on the regular retail price of Tenergy (at least here in the UK)
