Aztech Compatible Toner Cartridge Replacement for HP 58A CF258A 58X CF258X for HP Pro M404dn M404n M404dw MFP M428fdw M428dw M428fdn Toner Printer M404 M428 M406 M430 (Black 2-Pack)

I purchased a 2-pack of the Aztech black toner cartridges for my HP LaserJet Pro MFP M428fdw printer. Included in the box were the 2 toner cartridges, a pair of tweezers, a small pair of sharp cutting pliers, and what they call a "chip recycle drill," which is actually a pointed metal rod with a handle on one end that inserts into a plastic box that fits over the old cartridge . Detailed instructions were also included. I note that some reviews refer only to the tweezers, so it seems to me that after HP decided to basically embed the chip in plastic, Aztech came up with this drill. In a nutshell, as you turn the drill handle, it forces the pointy end of the metal rod under the chip, and pops it up out of the plastic. You can then remove any plastic and/or glue that is still attached to the chip with the pliers.However, when the drill got underneath the chip, it only partially cracked the plastic that the chip was embedded in. So I gave the handle another turn - not very forcefully - and the handle snapped off! In order to get at the plastic that was still holding the chip in, I had to get the drill metal rod out, which I finally did by using a big drill bit to grip the remains of the handle and get the rod out. I then proceeded to try to cut the plastic away, but on the first try, one of the plier blades snapped and went flying off (luckily not toward my face, as it's very sharp). I was able to use my own pair of small electrician's pliers to cut away some of the plastic. Then I managed to insert the blade of a tiny screwdriver between the chip and the plastic glued to the entire back of the chip, and eventually got it off.After all this rough handling of the chip, I figured it was damaged and I now had 2 useless toner cartridges. However, I put the chip into the new cartridge (that part was easy, and they have specific illustrated instructions to ensure that you insert the chip in the proper orientation). I installed the new cartridge and held my breath .... and it worked perfectly!! The copies are crisp and clear. I can't speak to longevity because it's only been a day.The instructions make clear that after installation, the HP software will continue to give you pop-up alerts that the toner is low, and that you can disable these through the printer software by putting the alerts on "snooze." I haven't gotten any alerts though.I emailed customer service about the broken drill and pliers. They responded within minutes. Since I will not need the drill or pliers to remove the chip from the replacement cartridge, I declined their offer to replace the tools.Despite the above ( the whole process took less than an hour, even with the complications), this is a great product and a terrific value. Just be very careful and follow the directions. You might want to wear goggles if you use the pliers. You can't beat paying $40 versus the $105 that HP charges. I don't know what they will do next to try to force you to buy their ridiculously overpriced toner; maybe wrap the chip in kryptonite?

This is one of the best things I have ever bought. It comes with instructions on how to remove the chip from the original toner. I was able to remove and instill the chip in less than 5 minutes. I’m a teacher and I use my printer a lot. I have told my principal about this toner and we will be ordering more.

We purchase the the Aztech brand of toner cartridges, since they provide a level of print quality comparable to HP's 58A cartridges, but at about 1/4-price cheaper! Where these are used, we go thru a cartridge about every 45 days. The lower cost is a relief.Note that we must remove and transfer the chip from cartridge to cartridge, but with the supplied tools, the transfer process takes about 30-45 seconds.We are satisfied with and intend to continue to purchase this brand.

These cartridges seem to work well however the chip on my OEM HP cartridge was certainly glued in! DO NOT USE the included "drill". You will need a sharp 3/8 or 1/2" chisel, the included side cutters and a good fine file. Remove as much plastic around the chip with the side cutters, be careful and be patient. Use the chisel to remove all remainder of the plastic from the sides of the chip. Then carefully chisel through the plastic base that the chip rests on about 0.5mm under the chip - do not try to pry the chip off the plastic. Use the file to clean off extra plastic from sides and bottom, careful not to file/damage the chip. Now it can be transferred. Worked for me, no trimming. However, the low cartridge warning is still on - which am not sure how to "snooze" it - i have a M428fdw and that option doesn't seem to exist. So i get these annoying prompts still.

product worked great with my printer.i had to call customer service and were super helpful and polite

**DON’T THROW AWAY YOUR HP TONER CARTRIDGE BEFORE INSTALLING THIS.**I ordered these toner cartridges because of the reviews and the fact that you’re getting 2 toners for way less than half the price as HP toners. Since I never read instructions, when I got the toners, I opened the box and installed it immediately. I kept getting an error saying it wasn’t working, so I got frustrated and went straight to Amazon to see if anyone else had the issue I was having. No one did, so I went to the box and grabbed the instructions. Once I went over the instructions, it took less than 5 minutes to install correctly. I’m glad I didn’t throw away my old HP toner before installing this one, because you need the chip from the originalHP toner in order for this to work.

I did not read the item description when I bought these and so was surprised to open the box and learn that installing these would be more involved than just dropping the cartridge into the printer. Although destroying the original HP cartridge using the screwy/punchy tool included with the cartridges in order to get the original chip was a bit of fun, but aligning that dang tiny little chip to get it into the replacement cartridge was not. I have not had any issues with the printer or any unusually poor quality prints since I got these, and unless a less expensive, same-quality option comes along, anticipate purchasing these again in the future.

1. You have to use a small screwdriver that comes with the toners, so you can prep it for the printer.2. I replaced my toner about two weeks ago, I don't use it often at work, and my toner is low.3. The shipping was fine and everything was as detailed, but I didn't have the time to figure it out, so I had to ask for help.
