some glitches but very good service
Without an independent lab analysis, I can't really comment on the product quality, other than to say that it seems to be ok. This was my second order: the first one went off without a hitch, but the current order had a few admin problems - the site was unable to work with any credit card or Paypal, obliging me to mail a bank draft, which worked fine but entailed additional inconvenience and expense. (My bank assured me that the problem was not at my end). The order was then lost in the mail, but the staff moved very quickly to replace it (adding a small bonus supply) and the second shipment arrived very quickly.
