There is a good level of quality with these cartridges. They aren't at the same level as OEM toners, but are much, much more economical per page for everyday business printing needs. It gets the job done and doesn't cause problems. I bought cheaper ones from Amazon and the toners had various problems that would manifest themselves before the cartridge would be depleted.

Always good quality for the price. It is nice to have access to this brand as an alternative to the ridiculously overpriced original cartridges from HP. I rarely have any problems with Moustache.

Good quality and fast shipping. I recommend this product.

ok toner but doesn't take long and it starts to streak

Working fine

Excellent product. Works great in printer and price is right!
