HP90X Black High-yield Toner Cartridge | Works with HP LaserJet Enterprise 600 M602, M603 Series, HP LaserJet Enterprise M4555 MFP Series | CE390X

HP toner carts have a built-in drum. That makes them seem expensive, because you're not buying the drum unit separately. The toner archives much better than after-market brands and is less-likely to have pages stick or transfer.

A little pricey, but HP brand stuff always does the best. Never get refurbished or factory toners. Stick with the originals if you want something that won't streak or leak.

Printing I can count on good product

What is there to review? It is toner and it works until it is gone. I guess it prints black and for a lot of pages!

I am super disappointed that I was not able to contact Amazon or HP to remedy this situation. I received a brand new, high yield toner less than 30 days ago and it is faulty. It is placing black dots on EVERY sheet of paper. When I switched the toner, the dots went away, so I know it's the toner and not the rolling mechanism. I would like this toner replaced with a new toner, as we have only used about 10% of it.

We use this for our payroll printer and another for billing. They last us a little over a year.

Original HP toner, easy to order, shipped on time and price was right. Toner is expensive but prefer OEM orver 3rd party

This is the high capacity tonner, it fits M602n/dn/x. It is also sold in double 90XD to save additional money.You can get a refilled ones from other brands, but it might cause damage to your printer, as the mechanics, of the cartridge, was not designed to rotate a second, third or more times 24K pages, and they reuse the core.If leaks you can call HP for replacement.The 4 starts is because they are overpriced
