My workmate put this straight into his printer and he said it works great! These came with the chip installed so no more fidling with the chip from the OME,Thank you for producing toners with the chip. 😊😎So prior, I'd had to buy an OME and it was so frustrating, took me over an hour to release one from one OME, bit by bit with wire cutter and then aligning with tweezer in the generic toner and it still didn't work properly so I was forced to pay the exorbant OME proces.

Use product for printing jobs. Quality of the print is excellent.

After a long search, LD is one of the few brands I now trust for non-OEM replacement cartridges. I can't tell you how many different companies I've gone through trying to find consistent quality. Our former local supplier's quality started off decent with great service but the quality dropped to a 60% failure rate. Sure they could get replacements to us within a day but it just wasn't worth the crap shoot on whether it would work at all or not. But every single LD cartridge has worked correctly so far across all of our different printers (all HP); I'm talking around 15 cartridges total.

It as as described and functions the way it was designed to do.

GREAT PRODUCT

Went through to about 40-50% remaining on toner cartridge and pages start turning dark and hazy. Of the 2 toner cartridges received, neither made it past 40%. Gave 2 stars because I was able to get 60% usage out of it.

Wonderful toner quality

Great Product. Fast Shipping. Will use again
