Let me start by saying this mount is a beast when it comes to suction power. I've tested it on my car windshield during highway speeds (70mph+), and it didn't budge an inch. The tri-cup design really does make a difference compared to single-cup mounts I've used before.
However, there's a big BUT coming. The plastic ball head that comes with it is absolute garbage. On my first test drive, my GoPro nearly became roadkill because of how wobbly and weak that connection point is. I immediately ordered a $7 metal ball head replacement - problem solved.
Here's my pro tip: always tether your camera when using this outdoors. Even with three suction cups holding strong, that plastic connector between the base and camera is scarily thin (we're talking 5mm thin). I've seen multiple reports of it snapping from just normal car vibrations.
The best use case? Smooth surfaces at moderate speeds. It works miracles on clean glass windows or surfboards. But if you're thinking about mounting this on motorcycle fairings at 120mph (yes, someone actually tried that), maybe rethink your life choices.
Final verdict: Great suction base ruined by cheap plastic components. Worth buying if you're willing to upgrade the ball head immediately and use common sense about mounting locations.
