You don't need any if you are trying to keep deer out. They don't work even as dense as 8/ acre.

I don't really think they work for the predator but they do look like a security system from the road. I ordered two and before 4 months was up, one has quit working.

If you have a cage with chickens, one facing each direction. We just got one to start to see how it works. So far, so good.

As many as your memory card can hold. Have another memory card with you to swap out if you ever fill up. Fellow photographers have given good advice here.

Only one. But you shouldn't need more than one - unless you screw up the application. I've been successful in 2 of 2 attempts, so have only ever needed the one.

A small amount. It is best to purchase a larger roll(s) and use it from the get go. Keep the small roll in case you run out of the others.

Yes . You need four. every 6 months they have to be changed. They have to be in use over the winter as well

It is similar to 'telephone,' so the more, the better. I would say you need at least 4.

I would use eight of them. I bought four, and though they held, I was much more secure when I bought an additional four and added them. They just do not cost that much for the peace of mind. Hope that helps.

your vehickle will tell you how many you need . I always have at least 2 backups because tire centers charge alot for them

Just one. It works for me because I have very limited space anyway. Take that into consideration for your needs.

When I ordered these, it said how many were in the box. We got 6?? I don't remember exactly, but I know we needed more than 2.

You need one for each device. As the picture shows, you can get by with two if one flash is on the camera and the other remote. I would get 4. one as a remote for shutter(hold in your hand), one on each flash (free standing) and one on camera.
