※※Important※※ Please "必ず" read the profile section if you are considering a purchase. There are two accessory shoes on the top (the light in the photo is for illustrative purposes and is not included). There are two screw holes on the top and one on the bottom, allowing you to attach lights, microphones, tripods, etc. You can securely fix your smartphone with screws, providing excellent stability. I bought this for YouTube shooting, but I rarely used it, so it's in good condition.
