Before looking at the models available here, I created and tested this balloon tying tool. I think the use is completely the same as the other models. The difference I find for me is that with this tool you can tie highly inflated balloons with a small knot. That was my goal. If you learn any other balloon tying technique, with this tool you can achieve the same result but on a highly inflated balloon. If you liked it, download, test and like it.
