I have been using the same Jet Tec compatible inkjet cartridges for the last 2/3 years at work and home. I have only had a faulty product once - which was swiftly replaced by Britink. On the E55 pack - JetTec have reduced their claim of '100% more pages' to 30% but still with 21ml cartridge content - they are better value than many standard or originals!
Have been purchasing Britink for a few years now - never had any problems with the quality (using non branded inks causes some people to be concerned) the delivery is always next day.
Your service cannot be faulted
Very happy with the Jettec ink cartridges and great value too.
GOOD PRODUCT FAST SERVICE KEPT WELL INFORMED ON ORDER STATUS.
