I can find no problem with the cartridges and would buy them again.
We have used V4INK for years & have had nothing but great results.
For the price and convenience of printing in my classroom, it is a great value.
I have been using V4INK cartridges for both HP and Brother Laser printers in my business for 8 plus years with excellent results and cost savings.I would highly recommend their products.
I've never ordered non-HP ink, but the cost caused me to read the reviews for this product and I decided to give it a try.
And I mean when the toner is first put in, not when it may be running low.
They work but two out of three had a broken plastic piece on the right edge --- never happened before with this product -- must be a packing problem.
This new one I put in today in my classroom is printing nice!
It ran solid black sheets of paper and left ink garbage in the printer to try and clean out.
No way to get the company to send a replacement so you're just out the money for the bad cartridge.
