Tied of paying through the nose for expensive Lexmark cartridges, I've tried various ink refills and compatible cartridges in my Lexmark S405 printer with no success. I am amazed that this 100XL black compatible cartridge worked. I'll definitely be trying the colour cartridges when they run out.


Very easy to buy, pleasant staff, amazing price, fast free delivery service. All round excellent service.


For use with my Epson WF-3520 printer. Great service, both in acknowledging my order, and its despatch and arrival. These were ordered as spares and so I haven't tried them yet. I came to stinkyink through a "Which?" article some time ago and haven't been disappointed to date!


Easy installation and good print quality for the usage I need and my printer (Lexmark Prevail Pro 705). I would certainly recommend these replacement cartridges for everyday usage and as very reasonably priced.


First time I used a 'Compatible' in my Lexmark S405 and found installation and print quality no different from dedicated cartridge. Still to install colour cartridges so hope they are just as easy. Did not get any messages giving issues as might have happened so was relieved. Price saving was considerable. Arrived a day early. So far, I would repeat order.


I have only used the black ink from the pack as yet, and find it has worked perfectly. I will review the others as and when I have to replace the ones I am using at this time.

Ask a question about this product

My machine automatically firmware updates... I found that compatible carts from others wouldn't print after one of the updates. Are your carts 'transparent' to the system? I also found other print issues like missing lines = blocked nozzles?


Although we did have some issues with the firmware updates when they first rolled out about eighteen months ago, we've since introduced the second generation cartridges of this range, which work just fine.

In the unlikely event of a problem, we fully guarantee all of our products for six months, so it'd just be a case of letting us know, and we'd take care of things for you.

I have updated my Lexmark S605 - will your compatible cartridges still work in my printer?


Yes, these cartridges will work in your printer. We stock 2nd generation cartridges which were made to override the firmware upgrades. In the unlikely event you did have an issue all our products are guaranteed for up to 6 months.
