MYTREX PROVE MT-PV22B I received an unopened item but am selling it as I have no opportunity to use it. The box has scratches and dirt. I have not inspected the item by opening the box, nor have I checked its operation. Please purchase only if you understand that this is a current condition sale. If there are any defects, please contact the manufacturer. Recently, there have been many people who request compensation after purchase. I cannot provide compensation, so please read the description carefully before considering a purchase. Free shipping. To minimize the shipping size, the item will be shipped with only cushioning material (bubble wrap) wrapped around the product box (see photo 9). Please understand that this is a simple packaging. If anyone can make use of it, please consider purchasing it.
