Thank you for viewing my products. If you are considering a purchase, please take a moment to read my profile, even briefly. The base mount and intermediate mount are from RAM. I believe the conversion ball is from Kaedear. With this set, you can attach a Kaedear smartphone holder. The base mount of the Kaedear smartphone holder is attached with only one screw. The RAM base mount is attached with two screws and a locking nut. The intermediate mount has some scratches. Please refer to the photos. Otherwise, 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 within 12 hours after the price is changed, I will block you. I will prioritize the person who purchases the item, even during negotiations. Thank you for your understanding.
