OfficeWorld Replacement for HP 364 364XL Ink Cartridges Compatible for HP Photosmart 5510 5520 5522 6520 B8550 C5388, HP Officejet 4620, HP Deskjet 3070A (2 Black, 2 Cyan, 2 Magenta, 2 Yellow)

Good delivery as normal. Well packaged product instructions include, problem I had was HP 5510 kept say non genuine cartridge.Must have removed and replaced a dozen times before the printer accepted them and allowed me to continue with non genuine cartridges.So to sum up great price, tidy product, BUT don’t think you can pop them straight in and that’s that.All working good now though.

I'm seriously impressed with these cartridges! I exclusively used original HP 364 cartridges for my printer until last year and wished I'd changed sooner. The original cartridges have very little ink in them, even the XL pack and are extremely expensive. My printer was also well out of warranty so there was no concern of the warranty being invalidated.I bought generic cartridges with a local supplier and couldn't believe the difference in price, for slightly less than the originals I got an XL pack with more ink than the originals and a spare black cartridge. These lasted me a full year. I would be a light to medium use user. So when they ran out I decided to try these, they were €10 cheaper than the local supplier and a double pack. Can't go wrong for that!The cartridges worked perfectly. Easily seated with no issues and even better no inky hands!I had thought the crispness and clarity of the print of my old generic cartridges was perfect until I seen the test sheet. Ultra dark, and completely crisp. No smudges or shadowing.Absolutely bargain price for cartridges, definitely won't be buying any other brand now!

What's not to like, fraction of the price and work just as well. Unless you are a perfectionist these a great for all sorts of things, especially if you have kids who go through ink like its going out of fashion. Probably best not to put in a printer still in warranty as if anything goes wrong you may find the warranty has been invalidated by using a non HP product.

For the price these are great quality and do the job. Only down side is one of the yellow cartridges was leaking on arrival. It was cleaned up but seems okay now. Just a bit of a mess and a faff.

I fitted these into a HP Photosmart B110a. I've had this product before and didn't bother writing a review, but it's worth mentioning that they obviously aren't official cartridges so your printer will likely complain after you insert them, but it's safe to ignore that message even if you are still under warranty. I always have the printer print a test page and sometimes align the printer heads with a new set of cartridges even if the test page looks ok. Lastly, best to replace all the cartridges at the same time instead of one by one, especially if they are different brands.

I was initially unsure about buying these because they were so cheap compared to original HP cartridges but the quality is excellent. They were recognised but the printer and work well. Some cheap ink cartridges can leak but I've not experienced any with these.

I've used replacements before, without issue. These are similar - nice thing is that printer recognizes how much ink is left, so an added bonus.

There is a reason why you should never use non-manufacturer ink cartridges and these are a prime example.My printer is compatible with the list on the description so I thought thatI would try my luck and order some cheaper cartridges to save a bit of money.I read the instructions that were supplied and my printer could not see them. I removed them again and checked the instructions again. They were installed correctly in the correct slot but the printer would not recognise them.I then decided to read other reviews and to see if I had missed something from the 3 instructions that were on the packet. One review said that there was a need to remove the Office World Sticker to expose the air vent.Why would I need to remove a sticker to make the air vent available? Surely the seller should be doing it otherwise, it's a serious design flaw.I removed part of a label that was so stuck to the cartridge that it was near impossible to remove.So I gave up.Save yourself a lot of hassle and buy from the manufacturer, you'll only have to complete a return and refund from Amazon.
