Compatible with hp 962xl Ink cartridges Combo Pack. 4 Pack

I use to buy used 61XL black from LxTek & Jarbo but decided to change brand. Boy, was I unlucky with this brand. Price were comparable and ratings were decent. My HP 4630 printer didn't have any problems with recognizing Upsek Black 61XL. Use it for 2 weeks, printed about 12-16 pages, then ran out of ink. WTF!1 ink cartridge down, 3 more to go. Will updated on how long the 2nd ink cartridge will last. Maybe the 1st one was a dud.Fun Fact- The empty Uptek Black 61XL cartridge weights heavier then my empty LxTek and Jarbo cartridge. Maybe the ink inside dried up.---------------------------------------------------------EDIT: 3/1/21I have been using my second Upsek cartridge for a little over six months now. The first one I used was a dud, but my second was good. I've printed over few hundred pages and still have some ink left in the cartridge. I have changed my rating to reflect my current experience. I still have two more unused Upsek 61XL black, hope neither of them are bad.

I have an HP 4635 and use off brand cartridges to save money. While checking out this ink, I was not out of ink, I just removed the black cartridge, loaded the upsek cartridge and printed a section of print. For comparison purposes, I printed a section of print with my current set up as well, before changing out the cartridge to write this review. This cartridge print quality is better. It may be because it is new and I needed to clean or align my old one, I print a ton of stuff for hobby and craft at home. I print ad materials and labels using label sheets. For this purpose I just printed a section of type in two fonts to see what would happen. The ink loaded asap, no issues at all. The chip seems great, communicates quickly with my printer, no lag time. Good value for two 61 XL black cartridges. I tried to post samples, the first I think is upsek, the second is the cartridge I was using. Which ever is better is the new, upsek cartridge. 19.99 at time of order. I'm just leaving this cartridge in my printer. It's good.

I purchased two black 61Xl cartridges from Upsek that are listed as compatible with the HP ENVY 5535 printer. The first one worked but was short lived as far as the number of sheets printed. The cartridge longevity was fine for residential use; I just do not print much. The second cartridge was rejected as incompatible with the HP ENVY 5535 printer. This cartridge could not be used.I /13/21 update. After writing this review, UPSEK. the cartridge manufacturer contacted me and refunded my purchase. I have changed my rating to 4 stars . As a consumer, products do fail and if the manufacturer makes it right that's all a consumer can ask. Thank you Anne!

I ordered these to have on hand when my other cartridge ran out of ink, which happened today. I put the first new cartridge in my printer, and the printer would not accept it. I tried it 3 times, nothing worked. I put the 2nd cartridge in and it does work, but now I am stuck with a useless cartridge that I paid for which doesnt work, and you are telling me I cant return it because it is after Feb 14. I JUST OPENENED THE PACKAGE. I would think normal people keep some backup cartridges on hand like I do and not wait to order when they are completely out of ink. What am I to do with this worthless, completely full cartridge?

I received my first set of cartridges and they did not work. After contacting the seller, they sent new cartridges to replace promptly. I received the replacement in just a couple days and it works great! I would say, don't buy if you're in a hurry "just in case" but if you have a couple days to spare in the event they don't work first go, save yourself some money and go with these!

I HAD TO PRINT AT LEAST 5 COPIES TO GET A CLEAR COPY CONSISTANLY

This is a decent HP 61XL replacement. Pleased with this purchase.

This is the second one I bought and I like it. It last longer than the genuine HP cartridge
