What can I say? - You get what you pay for.
I never use any toner cartridge other than the original manufacturers ones. Tried cheap ones and the quality and longevity of the printed results I found to be very poor and printer damage. These Brother ones for our LED laser printer produce consistently good results as do all of the Brother Printers that we use here.
There is a FREE recycling service too, pack the old toner in the box the new one came in, stick on a label and drop it in the nearest post office.
The address labels in the box might be for european addresses. I use the UK one which is based in Wrexham. Go to the Brother website (UK) and download a label: http://www.brother.co.uk/~/media/Pdf/BUK/Recycling/Recycling%20Label.pdf.
Excellent product, and save the planet with free recycling.
