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!
Great service and price
From my experience the colours produced by this Cartridge are as good as if not better than the originals at a fraction of the price - why pay the extortionate prices of HP.
Very good prompt and reiable service. Have been using this company for two years. never a problem.
If you haven't tried Britink yet , do it now ! it is a company that really does seem to care .
