This is fully compatible TN450 and is good quality. I am very happy with it

Purchased this product to use on my Brother HL-2270DW and looking for an alternative to purchasing brother hl 2270dw toner.
Never heard of V4ink but i did a ill research and they seemed legit enough for me to try their produce, and i could always return it to amazon if i wasn't satisfied.
Packaging:
The packaging is exactly as it is shown in the Amazon image, it was secure in the box.
Upon removal of the cartridge from it's static free bag, it had the protective yellow guard which is also shown in the Amazon image.
Installation:
The instructions weren't precisely clear because they seem to have left some steps out for printers other than the first one they mention in the instructions, but I figured it out without too much difficulty.
Swipe the green thing back and forth a few times and it's good to go.
It fit perfectly into the printers load piece and then slid right into the printer.
The cartridge was recognized immediately and my printer went to work by doing its initial start up process, same as it did with the standard cartridge.
Usage:
I printed a test page that looked great, so I proceeded to print 250 billing invoices.... each one looked the same as the next.
This printer gets used every day, anything that is Black and white goes through this printer and the ink seems to be very consistent and what I expect to see coming from a this printer.
Summary:
I will be purchasing this product again, probably in the 2 pack if it is available.
I would recommend this to anyone that needs a compatible Brother TN450 toner Cartridge
I think that it performs equally to the original manufacturers cartridge
Tip for manufacturers: have a different person who has never used the product try to follow the instructions for each product without reference to the instructions for a different setup. This will smoke out discrepancies like this one.
Anyway, buy it not just for money saving, it won’t disappoint you.
