I am not sure about the Longevity or quality since I recently purchased this product, but I would say buy it because It is doing a great job so far and the price is great for the quality of the print and the product !

I had no problem installing these and the print quality is great!

I had purchased another brand of toner for my printer and light lines like on a sudoku puzzle did not show. I was Leary of buying another off brand but decided to try this one and it prints those fine lines great! I will definitely purchase these cartridges again.
