Haven't had it long enough to determine it's full value but so far considering the price comparison with other stores it's a no brainer winner.

Works as good as the OEM brand cartridges. No troubles with installation or recognition by the printer. Once installed the cartridge functioned perfectly. Very happy with this purchase. I'll be sticking with the Moustache brand for the next toner order.

This is the only ink I use

I've been using these for years, work great

Can't beat the price, excellent quality

I use a lot of toner cartridges printing my book on Zambian trees, which I give to schools in Zambia and I am finding my costs have dropped since using your products.
