I got a new today from Amazon, so I put it to the test.
it actually works in my truck
It’s at a decent angle, so I can use it for driving, and not just vlogging
it’s stable and stays in place.
My truck vibrates A LOT, so it causes issues. It’s not viewable as much in the vlog because it is so dark (it was dark when I was driving home), but trust me, it kept flipping from horizontal to vertical the whole time.
