Some toners do not work as they are not the original, my fault for attempting that. Also, they are refilled, obviously, but put in individual bags and not even taped at the holes so you open each one and get caked with toner!

11/10/2016: the seller has contacted me and sent a replacement toner. Great customer service and product support. I shop here with confidence knowing that the seller stands for the product they sell.
Oct. 20, 2016: Second purchase was not as good as previous one. One week into the toner replacement and it already showing fading effect. I switched back to this seller because they used good quality toner but I believe the batch I have received was very old and substandard quality.
I guess I would need to look again for a reliable product.

Great service, item as described. Gross weight (toner+bottle) was 91.3 grams. The bottle itself weighs 16.8 grams hence about 75 grams of toner. Last time I bought from this seller it lasted about 6 months on very moderate use. I switched to another seller which didn't turn out good since the toner quality was very bad. I am hoping I will get a longer life from this purchase this time around.

This is a really good choice, I am a returning customer. The toner this time is better than the last time, expecially for its safty packaging. The price is low. So, really worth the money I have paid. Not only for the packaging, but also, it really can print 1500 pages. I used the last one for almost one year. I highly recommend this product to you.

I purchased two 2 packs of this toner.  The first cartridge was good in both packs, but the second cartridges are both bad.

First cartridge worked great, second one prints a 3'  blob every 4 inches or so, turns out the toner drum has a 1" long dent in it.  Looks new other than the dent.  Too late to return as well.  Grr.

I just installed the new toner two days ago and I'm already getting messages that the toner needs replacement.  For a mom who prints 5-6 homework assignments a week, this is bad.  I haven't printed ten pages yet.  My last cartridge lasted one year.

The first cartridge out of the two-pack worked for 5 weeks and then the printer says its out of toner.  No way it should be out that fast.  The previous cartridge lasted for at least 6 months.  We don't print all that much.

I purchased this product a year ago to make sure I had one when the toner ran out.  Well last month I tried using it as my old one was getting very light.  This one fit without a problem and the first print job was great, but it will not print but one job before stopping with a printer error.  Tried taking it back out and in again, and again it printed one job perfectly.  Replaced it with the old one again and printer working just fine but of course very light.  Since I also had a two pack from this supplier, I opened one of those and tried it.  Again only one job will print before stopping.  The package says it isn't OEM and that is correct it isn't.  It will not work.

I bought the drum and two toners a while back as a reserve.  The toners worked fine, but the drum is a loss.  It prints lines across the page.  Maybe it is the age of the drum, though I haven't had this problem before.  So 4 stars for the toner and 0 for the drum

I have to reset my printer every time I print something, it says I'm out of toner. I bought 3 and the 2 I've used say this. Only a couple hundred copies from the first, second one started saying it after first use. DON'T BUY THESE!!!!!! OTHER PEOPLE HERE HAVING THE SAME PROBLEM

I purchased this product on May 30, 2010. It is now Sept. 26, 2011, and I just ordered another cartridge. I am very happy with the quality of the toner and the length of time it lasted me, and I print a lot!

Thanks for speedy shipment, the toner was delivered in-time as expected.  I frequently have bad luck getting a good toner among Amazon sellers.  I have experienced receiving toners either built with a defective counter chip, or the black powder was semi dry up and I could feel the solid chunk while shaking it, or the gears making noise while printing...
This toner from "Renewable Toner" works great and prints smooth, and thanks a lot making speedy delivery.  I am the kind of person never prepare a spare toner!!!

There is a lot of secondary market cartridges available but these originals seem to last longer. Might try buying the loose toner and refilling them myself to see how that works.

Happy with the toner cartridge. I have ordered another one!

I got three toners last year in one package.  One toner made horrible noise.  The one, I just put in, did not print clearly as if it ran out of ink.  I suggest to buy something else.  Toner might cause damage to your printer.

used the first one and it worked decently. opened the second one and installed as directed and about 10 days the pages started all coming out with the powder on it and i checked inside and the toner was everywhere. this is the second time i have had a issue with one of the 2 out of the twin pkg.
lets see if the company really reads this response and decides to respond
