I hope nothing happened to both of your eyes and hands [this is the first time that I'm reading something like this], but how hard did you hit the punch tool?
Not hard at all. But, lets be blunt it was, as have been most that I have seen, a cheap made in China piece of crap.
I'm sure there are some seed plates makers that do not give you an automatic one give better manual ones.
But the last few generic ebay / amazon ones have really sucked.
<shrug> It is what it is, when you are getting something like this shipped to your door for under $15 you don't expect quality or durability of the plate or the tools. But it's still better then paper.
