I can't believe how easy the whole process was, even for me ! Everything was contained in the pack I received, including the return envelope. In fact the return was the only slight concern, as the girl in the Post Office tried charging me for postage that was already paid. My results came in the form of an email, in easy to understand English, and all was OK with my borehole supply. I would definitely use again and highly recommend Feedwater to anyone wanting to test their water.
