My wife has just had a fascinating morning with Amazon as we received 6 e mails yesterday asking for these to be returned as it has been found they only have 5% instead of 95% efficacy as found in Iceland - the country not the shop. I just want to let you know that you can contact Amazon customer services and get a refund for these without having to return them and go out to the post office and put yourself at risk - as you will find they will not give a return label as they are personal items - though to my mind they could have attached a return label to every order number to do this as the e mails were sent out with individual order numbers on them - of course they were automated e mails. My wife wondered if they needed to be returned as stated in the emails as they needed to be tested etc but evidently not. So rather than worry about posting these back if any of you have bought these from Amazon contact customer services. I don't know if other retailers have recalled them but presume they will. If I can I shall post the notice on here later.
Its a shame because they were really comfortable too. We have ordered more of a different make and hope we are not in the same position a few months down the line again!
