AztechCompatible Toner Cartridge Replacement for HP 78A CE278A Laserjet P1606dn MFP M1536DNF P1606 M1536 P1560 P1566 (Black, 4-Pack)

We have used these toner cartridges for a few years. Generally, they are pretty good. However, we have had a couple recently that seem to print unevenly at the left margin. Tried shaking the cartridge, and cleaning the printer drum, but no effect. We can work around it by adjusting the document's left margin but this is a nuisance.The accompanying photo shows how left most text & grid lines fade out. Switching to a new cartridge will likely rectify the problem, but it's a waste of money to keep doing this.

I purchased this 4 pack for the small, locally owned hotel that I work for. Being a small business it helps to be able to find items that we are needing for a reasonable price, this ink definitely fits the bill for that. Compared to other inks (especially name-brand) this ink is an excellent value for a 4 pack. We go through quite a bit of ink with our daily paperwork alone, not including the paperwork we have to print for the guests that stay with us.When the ink arrived it was perfectly packaged and appeared brand new, nothing about it suggested it was of a lower quality that name-brand ink.So far I have only placed the first ink cartridge in our printer and it has yet to run out (though I am uncertain how many pages we have printed). I have had this ink cartridge in for a few weeks and we have done quite a bit of printing since it was placed in the printer. It definitely seems to be lasting as long as the previous ink that we were using (which was also generic brand). I also haven't had any printer "warnings" like I usually receive from generic ink (non-hp ink, ink low, etc).So far I would have to say that this works just as well as any other generic or name-brand ink on the market, however, it is a much better value that many other ink cartridges that I have found. I imagine that we will continue to purchase this brand of ink in the future.

The cartridges hadn’t run out yet so I can’t comment on their life, but the print quality has been perfect and as anyone who buys toner knows, it’s very cost effective.

I purchased a package of 4 toners. Works well with my printer but doesn't print as many pages as an original toner. The third one I used left lines on the margins of all the pages and I couldn't use it at all. One of them had loose springs. Won't buy again.

Can't really do a good review on this having only used it for a few weeks now. Time will tell of its longevity. Print quality seems good so far. Price was right. Can't answer whether it's a good value for the money, or good longevity having only used it a few weeks. I'll have to come back and update this when the toner runs out.

Quality is as good as name brand. Used in pack & shop store on a daily basis

Of all the generic cartridges this is the least filthy, still alot of puffs of ink on my documents and not the greatest yield but acceptable for price.

Product works as advertised, and is at a great price point. This has been my go to toner for a while now.
