Review on CMYBabee Compatible Toner-Cartridge Replacement for HP 94A CF294A, Black, 4-Pack - for HP M118dw MFP M148dw M148fdw M149fdw M118 M148 M149 Toner Ink Printer by Kevin Folsom

So far this product has been good. I haven't had it long enough to see how long each cartridge lasts. Installation is easy - take out the old one, put in the new one - takes a second. Just remember to take the plastic strip out of the cartridge before installing it - the instructions don't say that and I tried to print and the pages came out blank (because the plastic strip was still in). after i pulled it out it worked fine.
