I’ve been using their eggs for several years. On multiple computers, have you found them to be every bit as good as the originals in a fraction of the cost.

Works just as well as the name brand.

Skeptical at the start but it works

These cartridges work as well as the brand name one, at a fraction of the cost. I've been using them for a couple of years and have never had a quality issue.

Always work on my HP B210

As the owner of an HP Photosmart 7525, I'm always on the hunt for alternatives to HP's very expensive ink. I typically get XL refills from Costco, which has each color (plus Photo Black) for about $10 each. Because of the pandemic, however, I was avoiding Costco and the OSIR seemed worth trying at about $11 for a package of two black XL cartridges arriving in a day or two. Verdict: the cartridges are fine, if I don't use them in my normal draft mode (to save on ink). The HP originals and the Costco alternatives both print perfectly in draft mode, but the OSIR has streaks and blurry lines on every page in draft. Switching to "normal" printing, the OSIR cartridge is excellent, but I'm not sure it will last as long as the original or Costco versions. That's the only complaint (the printer recognized they weren't HP, but didn't mind), and the reason for the loss of a star.

I like these a lot. Print quality is comparable to hp but the price is much better. Ive been using this brand for a few years now never had issues with leaking. The ink lasts a good while, too, although I’ve never actually kept track.

I have been ordering OSIR Compatible Ink Cartridges for years and always find the same quality and dependability. I am a student and printing is very important to my studies and due dates. The print quality is perfect and installing is very simple. I have found that text and photos reproduce in bright, clear, and accurate color.Each cartridge is air sealed to keep them fresh and a replaceable protective cover to protect your hands from the ink nozzle. I keep a full set of extra cartridges on hand at all times.OSIR Compatible Ink Cartridges are also earth-friendly in terms of printer recycle. I have an older printer that has performed well for years. Manufactures ink prices would normally make my printer too expensive to maintain and operate. Thankfully my printer has been saved from the recycling services since 2010. A remarkable 10 years of service.I highly recommend OSIR cartridges and appreciate the quick and reliable on-time delivery!
