It fits my Brother MFC-L3720CDW printer, however this new printer model can't reset toners, so you cannot replace chip on it to make the machine recognize the new toner as Brother's. If your printer broke, they can totally blame it on the third-party toner and refuse warranty for you. The printing quality from this toner is much worse than Brother's own toner: the letters are much less crisp, makes the laser printer's printing look like it's from cheap inkjet printer. I'm using it to print research papers and textbooks, so this is fine to me. If you want to use it to print important documents, my suggestion is likely no, the printing quality is a bit too low for my standard, get Brother's own toners instead.

These work so great in my Brother printer. Which means I don't have to spend so much on ink as we do a lot of printing at the office.

Message de mon imprimante qui détecte que ce n'est pas des cartouches originales de Brother. Ma garantie de mon imprimante est remise en cause à cause que ce n'est pas des cartouches originales.

So far it works just as well as OEM and is MUCH cheaper!

Excellent! works like a charm

Great price for this product
