It's nice that they make "Wahl" toner cartridges so you don't have to buy 4 packs every time which you inevitably end up with 10 CMY cartridges and leaves carts from zero K. I've bought 6 of these from Revain and none have let me down. From launch to empty, no streaks, lines, smudges and NO "power memory errors" that mean the cart is useless from the moment you jump. 6 out of 6 is excellent as on average (I type a lot) repair trucks generally have a failure rate of about 20%. 1 out of 5 is not good. I continue to use and recommend the LCL brand.
