What a fantastic product! :) Arrived in nice coloured professional looking box, with all the bits in it. A very nicely laid out instruction booklet complete with photos showing you every step, and the setup was dead easy. I don't know how much money I must have spent over the last few years refueling the printer with the standard Epson cartridges, but I can tell you it must have got up close to $1,000 cos I do a bit of colour printing. I have dated the ink reservoir so I can see how long the ink lasts for, but I suspect it will be quite some time based on how much ink there is! :D The ONLY problem I had, was moving the tube clips, which needed to be shifted a little. The booklet simply says to pull the tubing through the clip, but this is not quite so easy, as the clip really grabs the tubing. Out of fear of actually snapping the tubing, I gently removed the clips from the tubing, then repositioned the tubing, and gently put the tubing back in. This is the ONLY thing I found an issue during the installation - the rest was a piece of cake, and the printing is excellent. :) It was quite amusing to see the ink being sucked up the tubes when the printer did it's new cartridge initialization routine. ;) I will be recommending this system to anyone with an inkjet that does a bit of printing.
