Replacement HP PhotoSmart D7500 Series Reviews

Ink level indicators on HP C310a operate just as with genuine HP cartridges. Not sure about life expectancy yet.

I've used several companies to buy my cart's but not anymore I have 1 company I use at Mikes Model Car World and that's Combo Ink .com Thanks Mike

Their service is great. Their product is great. I like the ink better than the HP Manufactured Cartridges.

The ink level indicators work like the original. The clear sides make it easy to verify the ink remaining.

I got 2 sets of photo inks and one extra black, total of 11 cartriges for the same price as walmart wanted for just one set of photo cartriges, whch was 4 small cartriges, they work just as well, cant tell the difference, well done!

A year ago I tried a sample of these ink cartridges and was disappointed in their performance, they would not allow the HP printer to print, not even in monochrome. I waited a year and tried again. This time they performed very well, the printer works like it had the OEM products. The package clearly states the ID Chip is installed for each cartridge, and that on some models the Ink Levels may not show in the printer interface, mine does show ink levels. There are a few minor differences between the ComboInk cartridges and the OEM cartridges; one possible problem in the future, and one improvement. 1. On the bottom of the cartridge there is a tiny orange plastic tab to remove the seal for the air intake valve. This tab does not completely remove the plastic seal covering the air vent system and could cause the cartridge to fail after several uses. As ink is used the vacant liquid causes a vacuume to develop inside the cartridge, this vacuume must be replaced during printing via the air vent system. 2. On the bottom of the cartridge, at the print head, there is a large plastic seal, with a large orange handle to remove the sealing cap over the print head. The OEM version has this tab fixed to the body of the cartridge with tiny struts, when removing the sealing tab the struts are broken off preventing the tabs from being used to re-seal the cartridge. The ComboInk cartridge has this similar sealing tab, but with a cam type securing device, this allows using the tab to re-seal the print head in the event the cartridge needs to be sent back to the factory. Overall I am pleased with my purchase. The photographs and documents I have printed are of very good quality.

I have only used the first cartridge for a week or so, and it has worked flawless so far. I will update another time.

I had a Black Cartridge quit working. Had message on the printer. Called ComboInk and they shipped out a replacement without a hassle. Outstanding Customer Service. Pricing is much better than other sites I have visited.

I use the product daily and it has performed as good as original cartridges.

I love the great prices on the ink bundles. Even though I buy the XL cartridges, they seem to use up fast unfortunitely. I do like the clear chambers so you can actually SEE when there is no ink left, despite that your software is telling you that it is empty.
