Since it is a genuine product, there is no problem in use. Delivery date was delivered within the displayed deadline. Regarding price, recently it can be easily examined on the net to compare and consider, but there were places for goods including goods delivery including the shipping fee included in other companies for this product. It may be difficult because we deal with enormous items, but I think that customer satisfaction will be raised if the prices of other companies are also studied and always provided at a cheap price. I expect it in the future.
