Best Automatic Cone Stuffer?

Hows it going guys?! Just wanted to get on the page and see if anyone has had any experience with automatic cone filling machines?

Thinking about getting a knockbox or a reefer ranger as the reefer ranger is about 1500 cheaper but can’t find many reviews. Let me know if any of you have experience with any of these machines, and what you like about the ones you’ve used and why.
