Product review (1 stars): Very Disappointing!
This product is very disappointing indeed! (My filter had the latest ProOne D Filters) Firstly the screw to attach the knob on the lid is too short.  Secondly, the first run of water took around 8+ hours to go through, which I accepted as understood it is slower the first time, this water was thrown away as per the instructions and filled the unit again, the water took all night to go through, and the water still looked a funny pale blueish colour and tasted awful, but yesterday evening at 10pm I filled with tap water to the top, this morning at 9am only about a quarter, if that, of the water went through the filters, so there is very little water to drink from the system as the water is still sitting in the top unit! It's now 3pm and the water has not moved through the filters it's still in the top unit!  Fortunately, bought from a company in the UK, received this Tuesday, so today being Thursday believe I am entitled to get my money back under distance selling and via my credit card company, which I'm now going to put a stop on. 15 Delivery, no idea what it's going cost to send back and if the same cost that's 30 down the drain!!! It's pot luck if you get one that works. What a waste of time and money! :(
