Bought one last fall of 2023 and like what has been mentioned is the simplicity of the unit and easy adjustment from one caliber to another. Then you have the price, couldn’t justify extra cost of other models. Works! Best to all!
A comment for Al gores ribbons. Some people are like slinkies, they are not really good for anything but they bring a smile to your face when you push them down the stairs.
I use butane so it takes longer but I let it go a little orange/red and so the flame changes colour for a second and a half or so. It's not enough to get it to the right temp for a split second. The softening of the neck and shoulder does take a second. You also won't burn the metal... Better to leave it a second longer and get a good anneal then not do it long enough and get uneaven results.
That is what the knob control does it will speed up slow down the spin. I use glow method for time in flame and you may under/over a few cases. However easy to change.
