Vmosgo 5-Pack Compatible with HP 201X Toner Cartridges 2 Black 1 Cyan 1 Yellow 1 Magenta, High Yield Work with HP Laserjet Pro M277dw M252dw M252n M277n Printer (CF400X CF401X CF402X CF403X)

I use these cartridges in my HP277 laser printer and they work just fine. I avoid doing firmware updates from HP to avoid the issue with third-party cartridges not working. Think about it if your printer is printing just fine, why do you need a firmware update?I always check every new laser cartridge for leaks before I put them in the printer. None of the cartridges I've gotten from this group have ever shown a leak.Print quality stays good, like every other cartridge over time the color will fade letting you know it's getting low. I usually get a message from the printer long before these cartridges fade. I squeeze the last out them by taking them out and shaking them. Still no leaks.Upfront: I have purchased 3 sets of these and the company sent me a free set for my review. This is an honest review if the product sucked I would have said that.

It is cheap. So one would wonder if this is worth it. I did have a problem with the first cartridge. However the customer service was exceptional. the replace it without any issues or questions, it was here the next day.I print on a variety of paper - plain, glossy, thick cardstock, thick labels. The ink has consistently come out like it was printed. I do engaged the vivid and best gloss on the printer options. so this amplifies any issues but also shows up if the ink comes out well. I am reluctant to say this however I am very impressed that the print is better then HP's ink which I have used for many years. I don't know what made me try this and it does work very well.

I'm on my third set of this toner. And I have a full box of bad toners. For some reason, they leak. The first page you always print will have blue or red in blotches on it.Things Ive encountered:Red toner leaks randomlyBlue toner drops splotches all over the pagesOne yellow toner printed more green then anything else.2 Blacks have leaked and printed ghosting images all over the pages.It seems like some people have had good luck with these, but we keep having issues.

I question the use of the term "High Yield" as the black cartridges printed less than a third of what the legit HP cartridges have for me. Now that the color cartridges are in, the magenta leaks after the printer has been sitting a while so there's a splotch in the top left corner on the first page of the first job each morning. They were definitely worth a punt and the price was great, but I feel like their QA leaves a lot to be desired. You might get lucky, but after these are done, I'm going back to genuine HP cartridges as I don't have the time to screw around with this.

The price was great. However, when I started printing I noticed there were blue dots on every paper. I tried running a cleaning page... that did not work. My Pinter has never done this before. The company was nice enough to refund my money, so that I can replace the faulty toner cartridge.

The first set I received leaked onto the printouts (see pic 1) and when you go to clean them to try to get one good clean print you can see all the ink that just falls out of these (see pic 2). I contacted support and they offered free replacement on the faulty cartridges with no hassle. Hoping the second set does better. Couldnt ask for more when it comes to supporting what they sell.

Cartridges work well for a short time, then began to leave colored streaks and blotches. Look elsewhere for better quality replacements.

sorry for a negative review. I purchased these. The blue cartridge leaked over all the pages and caused blue streaks on every page I printed, in blobs and streaks. The blue toner was sprinkled throughout the printer itself. the Magenta was not as bad but still streaked the pages. The Yellow and black seemed fine.
