i have a tapcooler bottle filler and really love it. way easier to user than a beer gun. the only think i don't like is that is is a bit slow and having to hold the bottle can be a pain. i saw that there is a hands free mount that hooks to the filler and holds a bottle into place. i wanted to see if anyone has used this and if so, how well does it work. i feel like i have to hold the bottle pretty firmly to the silicone seal to keep a good seal and have the counter flow filler work like it's supposed to.
