Review on 🖨️ Cool Toner Compatible Toner Cartridge Set for HP 131A 131X Laserjet Pro, 5-Pack by Epickson Palma

updated 7/20/17. I contacted the seller, Cool Toner and within 48 hours they sent me a new cartridge to replace the half used one that was leaking. I couldn't have asked for anything better and have changed my rating from one star to five stars. Thank you Cooltoner! Updated 07/18/17. These cartridges initially work fine, but then streaks appear on the left side. I've tried cleaning the cartridge rollers (they don't spin so I can only reach one side) and the printer rollers. That's enough for about 5 copies and then I get the queue back. I use this for work and cannot send documents that look like this. There seems to be a lot of toner left in the cartridge, but if I have to throw it away to get rid of the line, the cost goes up. I do not know what to do. Updated 03/20/17. It seems that these cartridges are getting cheaper, but so is the quality. The first cartridge lasted me about 6 months. The last one was leaking and only lasted about a month. I'll see if there's an alternative. Initial 5 star rating: I originally bought this toner cartridge because the price was right. Each cartridge lasts about 6 months. I use a Canon printer for work so it gets used quite a bit. Recently bought a third cartridge. I can't tell the original cartridges from these. I highly recommend them.
