I paid for a next day service and although i received the bottle to return the next day it took a further 2 weeks for the test report to come through. I believe it would have been longer than this if not for a couple of phone calls and 2 emails to prompt the test to be done. I was under the impression that the test was done in house (as stated on the front page of the website) at feedwater but the test was actually sent away to a further lab to have the test perform which only added to extending the timeframe. Not best pleased considering the cost.
