I have been using Jet Tec cartridges for several years and they are as good and possibly better than the originals (they contain more) and Britink are also great
Have used Jet Tech for some years and had only one problem which was sorted out immediately by Customer Services.
The best company selling this type of product I have dealt with
There is never any problem with my printer accepting these cartridges. They never clog and give great printing results. At the price why would you ever consider buying originals. Also fantastic service, they arrived within 24 hours - thanks guys!
A first class product and first class service, you cannot find better.
