Thank you for viewing this item from among many others. This is a Kaedear smartphone holder. It's the separately sold air absorber set from the same manufacturer. Although it's attached in the photos, I will remove it before shipping. I think it can be easily installed by looking at the instructions. Since the included base mount is not available, please prepare a separate 17mm ball-compatible mount. Only the main unit is used, so the wiring cords are unused. I've used it for about 3 months after purchase. There are no noticeable scratches or stains, but please refrain from purchasing if you are sensitive to such things. - If you are interested in a price reduction, please provide your immediate purchase price. If the item is not purchased after 12 hours of the price change, I will block you. I will prioritize the person who purchases the item, even during negotiations. - I do not offer exclusive listings or holds. Thank you.
