To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This appears to be a lower quality than the Arlo branded product, and whilst reasonable value it's much fiddlier to attach a camera to when it's fixed the wall and you're at the top of a ladder. Needed it, and it's up, but wouldn't buy again.
Not suitable for Arlo Pro 2 if you're going to have the camera permanently connected to power. The power connection is very close the the mount screw on the Arlo which means you cannot tighten the locknut.
