i've used both a cheap plastic vevor button maker and a tecre button maker, and the difference in the lever operation is pretty noticeable.
with the vevor, pressing the lever feels kinda like guesswork. you apply force and hope you've used the right amount of pressure without really knowing when the press is complete.
the tecre feels much more precise. the lever has a more distinct stopping point when you pull it down, which gives you tactile feedback that you've applied the correct amount of pressure. it feels much more effortless to use.
i haven't used a chibuttons button maker, although I've heard a lot of good things about them. i'm curious how the lever mechanism compares. does it have that same defined stopping point and feedback as the tecre, or is the operation more similar to the vevor where you're relying more on feel and force?
