We've come to rely on Monoprice for all sorts of items. We purchased some inkjet cartridges in the past, and had great success with them, so we decided to try laser toner. Monoprice has a great price and the toner works as it was intended. Thanks, Monoprice!
This initially seemed like a good alternative to the $75 official Brother toner but after about a month it began to produce a two-inch bar of gray on the left side of every page. This makes it unusable for printing any professional documents.
PROS: Prints well for about a month.
CONS: After about a month, the toner started producing a two-inch gray bar along the side of every page.
For Intellifax 2820 (maybe others) Toner works fine, but when you remove old one from machine it removes both toner and drum, you have to remove old toner from drum, attach new toner to drum, then reinstall.
