I have been using their compatible cartridges for a few years. I was cautious when I first bought them, having previously had problems with cartridges from two other companies. However I have always found their cartridges to be of good quality and at the lowest prices, I have never had any problems with them. As they are local to me I usually buy from their shop where the staff are very helpful and friendly. Recently due to covid I ordered over the phone and received the cartridges the next day. Why pay ridiculously high prices for original cartridges, these are just as good.
