The tri flow tap I bought looks and feels very good quality but I have not had chance to install it yet so I can't comment on it's functionality. The reason I have to give you a rating of 'poor' is because you did not include any paper installation instructions or manual with the tap but you sent me a link to a Youtube video - which I find unacceptable. I rang and requested the installation guide and manual as a PDF document I could keep on my computer and apparently you don't have one. For a tap at this price I would have expected a paper installation booklet in with the tap.
