ULIBERMAGNET 24lb Magnetic Camera Mounting Base with Mini Ball Head, Super Strong Rubber Coating Neodymium Magnet with 1/4’’-20 Male Thread Stud for Mobile Camera , Security Camera.

Looks like a good quality product. Magnet is strong and is able to hold my Arlo Pro 5 cam.

It's great for attaching a camera to side of a metal building. The magnet is very strong.

I got this for a camera and it does well for that purpose. Only thing I wish was better was the knob to tighten would be better and that it came with an Allan wrench. Other than that not bad

Good quality product, but did not work for my needs. Note that the ball on this mount is 20mm (not 25mm).

Awesome accessory for any motorcycle that has a steel tank.

THIS IS PERFECT FOR MY AUDIO RECORDER

great, used on tractor

I'm using this for a work light in the back of my pickup which weighs about 8oz. The magnet is plenty strong but the ball mount won't tighten enough with my fingers to hold it in place. I used pliers and it holds fine but that sort of defeats the purpose of being versatile. The small knurled knob should have a lever to tighten.
