This is the second time I ordered this toner. The previous two replacements have lasted me almost 4 years. This is with two high school/college students. This toner works beautifully and is inexpensive. I will continue to only purchase through Monoprice for printer needs.
PROS: The price is excellent. Even including shipping to Canada this is still 1/5 the cost of a Brother toner. The quality was similar to Brother ie it worked.
CONS: I am not sure if it was the amount of text in the project but the toner did not give me the volume of print I expected. ie 1 cartridge produced about 1200 duplex pages of legal print (2400 images). about 1/3 of the advertised quantity.
PROS: We have ordered the tone cartridges from Monoprice in the last 6-8 months and have been very pleased with this product. Copies are clear and price is great! We use a Brother copy/fax/print machine that had poor copy quality when printing from a re-filled toner cartridge from a local dealer. Monoprice cleared up our problem.
