Buyer beware.
SIS is fine until you need to send back the purchase. No such thing as free shipping on returns. You have to ship at your cost and then they deduct from your refund their shipping cost to you. Also, they deduct the unreasonable “restocking” cost of $9.00! Really??!! When paying top dollar for a product, shipping should be free. I would have had that experience had I purchased the product direct from the manufacturer.
