Whew, respect for her to invent this at such a young age!
I think I would love such an easy girth tightener, especially when it's cold in the winter, the straps are slippery with rain and my hands are frozen...
Not only the tightening can become problematic then, but even more annoying, the loosening! Of course you shouldn't pull them too tight in the first place, but even when it's okay those stupid straps can make it quite hard to fasten and loosen the entire thing.
Another plus side for this system is that you don't pull your horse to the side when pulling up the straps. When the father tightens the girth in the traditional way, he seems to throw over the entire pony with the force he uses to tighten the girth. With the pulley system, you simply pull down and the horse can stand still and balanced in the meantime.
What I liked, was the way the little girl with the white pony fastened the girth with a simple, soft downwards pull because she didn't use any pressure at all and there wasn't any overtightening either. But when before that the inventor fastened the girth on the chestnut pony, I actually was quite shocked to see how tight the girth went. Instead of keeping the saddle in place with the girth slinging tighter around the belly, it actually pulled the saddle down into the horse!
I think it would be a great thing for handicapped and less strong people in slippery weather like me, but it sure would need a warning label in order to tell people not to pull it too hard, and what happens with the chestnut pony in my opinion is way too hard already. I don't see how you can place a flat hand underneath the girth like that, and that should always be the case.
