i don't know why i'm buying gopro suction cup only now but this is my first one. At first glance, the diameter of the suction cup is much wider, around 3 inches, while my usual mounts are 2 inches. Those are all my rough guesses. The reason I bought it was to use with my slightly heavier aluminum gopro housings. I wanted something with a larger diameter but didn't want to use my 6" suction cup mounts. Either way, this thing works surprisingly well! I once forgot to attach it to a car going from Santa Rosa to San Francisco! To say the least, I was concerned, but he held on! FYI: I've read a lot about people having gopro problems -Suction cup or something had similar. Brackets become loose or lose suction power. I've made countless YouTube videos of me installing my gopros on all my vehicles, usually 2-3 independently installed gopros. So far I only had one suction cup that lost its suction power. My secret is making sure the surface is smooth and clean! I always wash the surface with water. Just pour some water on the spot and brush it off with your hand. Watch out for watches or jewelry. I make sure to keep the area slightly damp. not wet, but j It is enough to wet the suction cup when applying. If it slips I will rub the area a little more but not dry it completely. I've had great success with this method and it has worked to at least 85 mph! (Texas has an 85 mph speed limit).
