T***r –
The product i received about a month ago arrived broken. I was asked to return it in order to receive a refund. Since i was on a long vacation abroad, i could not return it to the seller. As a result, i contacted the seller and explained to him that i could not return it. To my delight, the seller accepted my request and sent me a new product in place of the broken one, even though i did not return the broken product. The seller is very honest, very reliable, and attentive to his customers. I wholeheartedly recommend purchasing products from him. You will not regret it. The replacement product i received works excellently, and the finish is of a high standard. Highly recommended.
