Unethical business practices, cartridges incompatible and sold half empty

Really poor service from Ink Star, the company is unethical in their business ways. They sell you cartridges which are almost empty, when you return it in the original packaging they weigh it and say you've used the ink, and refuse to refund you. Unfortunately honest customers is at a loss here. Also the cartridges is not compatible as they would claim on their website.

Karma...what goes around comes around. Please do not buy from them! What a rip off company
