I have a few of these for my cameras I put on public land. They can be loud and rattle in your bag when transporting in the woods but as far as security for a camera on public land this is the best product out there.
I do like the security box. I have one for each camera and the material is very good. And it has a few different ways to mount it along with a security cable.
We have a lot of black bears where I hunt in WV. These boxes work great! I need to order some more. If you are considering buying them for bear issues don't hesitate.
Mysterious things kept happening to my cameras, until I installed a locked armored box around each one. If you have that issue like I did, I recommend using the box and mounting it to something very strong.
