I got to the barn as the ponies were being brought in to be fed, so I put this on Miss Greta, took pictures, and then see how she was being led around in it. Firstly, she was a lot more sensitive to it than a normal halter (she doesn't take much convincging now, anyway, so it was noticeable) so I will say I'm a believer now haha. I will get a nameplate soon :)
As you can see in the pictures, Greta decided she needed to sniff the camera first, to make sure it could capture her properly I suppose. I guess horses can sense those things. She also needed to put on that sultry, disinterested look like the professional models do. She's on her way, I'm telling ya!
