Rating: - Erratic results, great concept
Foremost, I like the idea a lot and having been using it frequently about a year (been refilling my own cartridges for 8 years). However, the results are inconsistent - sometimes it fills completely and other times it does not (even after repeatedly pressing the pump). My first choice is to try this drip system and let it sit for 2 hours. But I now always check the handy calibrations on the tank. When it does NOT fill, I revert to the manual syringe (yes, messy) filling. The Dataproducts system is quick, but not consistent.
Rating: - A MUST have product that saves money
I was really skeptical when I first bought the refill system for my HP 56 cartridge, until I tried it out. I followed all the instructions carefully and presto! My cartridge was filled and was working perfectly.
I used to buy new cartridges, then I switched to remanufactured cartridges at those office supply stores, then I would use the remanufactured ones and send it down to my local pharmacy store that offered refill services for $10. Finally, I got so fed-up with buying cartridges and the pharmacy place kept telling me the cartridge failed to work, I got the easy to use refill system.
One big tip: Refill often, don't refill once it hits empty. If you start seeing your printouts looking faded (the signs of an empty cartridge), stop printing and refill immediately. Once the cartridge runs dry, you risk severe damage to the cartridge and may cause failure to work properly even if you refill it. Preventative maintenance is the key, do it about every 150 pages.
Rating: - works great, saves $
works great for my HP21 cartridge. no need to drill holes. no need to tape or glue after filling. just carefully peel back the label on the top of the cartridge to find open fill hole. fill, then fold back top label to seal. works great.
only wish they included a trick for getting the HP software to reset the ink level (it still thinks it's empty). not a big deal, just refill when the print quality starts to change...the gauge isn't accurate anyway
Rating: - Works as promised
This one works. I've tried some of the other products and had a mess. This was clean, did what it promised and the ink quality is as good as the name brand. By the second refill you've saved more than the cost.
The 3-color is trickier but just stay calm and exactly follow the directions.
