After noting the considerable difference in price between these cartridges and those in the local stores, I decided to try these. Unfortunately, the new cyan cartridge leaked toner. So this review is about the incredibly good warranty after-service.
I called the company to let them know of the problem. They shipped a replacement cartridge FedEx the same day and gave me a return RMA for the defective cartridge. The RMA required a credit card # for the value of the cartridge, but as soon as it was received, I was notified that there was no charge.
I have now run more than 1000 copies of multicolored pages without a hitch. I will purchase from them again.
Misleading yield information 
2008-03-03
The product information indicates that there is a yield of 5,000 pages. If you look at any other toner, the yield is per cartridge. If it is for a set, then the number indicates how many pages you can expect at a certain coverage. For HP brand toner, the yield is 2,000 for color and 2,500 for black. If you buy a set of HP brand toner, you can expect to get about 2,000 pages - you typically use all four colors for color printing.
This MIPO set indicates a yield of 5,000 pages. I just installed the three colors and my printer tells me I have 999 pages left. I haven't installed the black cartridge yet, but it is obvious that they have inaccurately listed the combined total of pages you can get from the set -- this is misleading, it is not consistent with how anyone else does it, and it isn't even correct (assuming the black also has 999 pages).
This same supplier has another generic set on sale at Amazon for $249.89.HP Compatible Full Set of Q6000A Q6001A Q6002A Q6003A (B,C,Y,M) Color LaserJet Toner Cartridge (Color Laserjet 1600, 2600n, 2605) And, you can get real HP toner (OEM) for no more than $320 on Amazon or $324 from HP (free shipping).
This product cost me $295 with shipping. At 1,000 sheets for the set that amounts to $0.295 per sheet vs. $0.162 for HP at 2,000 sheet yield (not including higher yield on black). If I get 2,000 sheets it would be $0.147. If I get 2,500 sheets (as I am now told I will - see below) it will be $0.118.
They should fix the product details - why would anyone purchase this product, except to get a higher yield? Would you buy a generic if you knew you could purchase the brand-name version for 10% more and your cost per page would end up being less?
I was willing to take a chance and purchase a refill. I knew the quality might not have been 100%, and that was okay. I would not have purchased if it hadn't been for the significantly higher yield.
I wonder what the yield is of the $249 set shown above (manufactured to HP's specifications)?
****I spoke with my Seller - Best Source Office Supplies who checked with MIPO. It is a big company, and is supposed to be one of the better ones with refills. The colors are good so far. They think it is a chip issue and the cartridges will actually yield at least 2,500 pages or 25% more than OEM. We'll see, I am keeping them. If that is so, it would make them cheaper than $290 for an OEM set (CompUSA) ($0.118 vs. $0.145). Not as bad as I indicated above, but not a 5,000 page yield. If you want a good quality generic cartridge, this is probably it - and presumably most of the chips show the correct yield.
The color cartridges don't work 2008-02-19
I ordered the package of four cartridges for the HP 1600. The black seemed to work somewhat ok, and started really fizzling out around page 1000. The color catridges seemed not to work at all, although blue did work some. I was severly disatisfied with this product.
Nice cartridges, not packaged for shipping 
2008-01-25
Based on the price (and it *is* seductive, is it not?) I decided to order this four-pack instead of HP-brand. My first surprise was finding that although these are marketed as a pack, they arrived by individual boxes. And those boxes, alas, are *NOT* designed for rough handling! HP's toners are packaged in tough bubble-wrap-style inner sleeves; these are packaged in flimsy cheap foam padding. The black cartridge (the only one I've opened so far) was broken and will only print on half the page (all it took was a small bit of plastic to snap off).
So cheap is as cheap does, I'm afraid. I can't even rate the quality of the toner at this point, since black is non-functional and the original color cartridges are not quite finished yet. Meanwhile, I need to make a run to a local office supply store to pick up a new cartridge for a printing project.
The packing slip advises the customer to "CONTACT CUSTOMER SERVICE WITH ANY QUESTIONS REGARDING YOUR ORDER" -- and then doesn't give a phone number or email address (I got them from Amazon). I have a call in to the company (no one answering the phone) and we'll see if I can get a usable toner cartridge out of the deal, eventually. The email address is a Google Gmail account, btw, which does not give me a warm feeling about the financial stability of this company.
But yeah, the price is *really* good...
Good choice. 2007-11-22
I didn't want to spend $320 for cartridges for a printer that cost $299.
These cartridges appear to work just as well as the HP's that were in the
printer. I would buy these again based on my experience so far!
Excellent! 2007-10-30
The seller had a quick exchange, great service, and the product worked wonderfully for the product in our office and at such a low price!
