Review on High-Yield TN-336BK/TN336C/TN336Y/TN-336M TN336 TN 336 Printer Toner Cartridge Set - HI-Vision Compatible, Black/Color Combo, for HL-8250CDN, HL-8350CDW, HL-8350CDWT, MFC-L8600CDW, MFC-L8850CDW by Charles Chambers

I really liked these HI-VISION toners. They are inexpensive and, for the most part, work well. My only complaints: 1) Some of them come with an empty flag. When you load toner into the printer, you will be prompted to replace the toner. There are two options: remove the endplate from the toner and reset the gear, or use reset on the printer to force it to ignore the gear flag. 2) The last batch of toner is leaking. This is frustrating for several reasons. Firstly I have to replace the toner before it runs out and secondly it ruins the printout.
