As another review posted "Do not order from them. If they send you a bad or wrong item, they simply refuse to acknowledge the error".

Caveat emptor - the fact that buyers typically have less information about the good or service they are purchasing, while the seller has more information. The quality of this situation is known as 'information asymmetry'. Defects in the good or service may be hidden from the buyer, and only known to the seller
