I have been buying V4INK toner for Brother printers for about 4 years. In those years there was only one problem, and V4INK replaced it with no problems. I still have a Brother printer and since I've had so much luck with their Brother products I decided to try replacement toner for a couple of my HP printers. make it difficult to use third-party inks. I was a little worried they wouldn't work, but V4INK sent very clear instructions on how to get around this, so installation was quick and easy. Print quality and colors appear identical to OEM toners. I printed a test page I designed with some photos and very small and large characters and I didn't notice any difference. I can't say how long these toner cartridges will last, but time will tell. If they work and last as long as the replacement V4INK cartridges for my Brother printer, then I would expect the same life as the OEM cartridges.
