Having bought the printer and hardly used it because of the extortionate cost of cartridges I decided to give a CISS a try.
Easy enough to install - no issues except a bit of air in the lines but that was my fault.
Results thus far - one perfect A4 colour photo - wow. I have a printer I can use without taking out a mortgage ! Very happy with the product and would not hesitate to recommend.
Oh, by the way - I opted for 24/48 hr delivery - the order was placed in the evening - CityInkExpress despatched the following day on Parcelforce 24hr Express which probably cost them more than I had paid for. I was impressed with that !
