Hi there, thanks for your questions about our compatible cartridges.
To give you a fair answer, no they won't be detrimental to your printer as they are similar to the original Samsung so there is nothing in the toner that would make it operate in any different way to the genuine Samsung toner. What's more, we manufacture all our compatible Samsung cartridges here in the UK to the highest standards, so they are of the best quality, would cost a little bit more than most compatibles but you aren't paying for something shipped in from China. This is why we offer a 3-year guarantee because we stand by our quality and it gives you the utmost confidence.
With regards to the quality of the print, they will never be as good as the original Samsung so we always advise that if the quality is very important to you then you may want to remain using the original, however, they are at the highest scale of quality for compatibles and our warranty does cover quality so give them a try and if you aren't happy then we will take them back and offer a refund or exchange.
