<human>: Can you succinctly summarize the text in 1-3 sentences?

Technically my first post here, since my real first post was removed. Apparently turning a hard drive into a floppy disk is "too common" of a mistake.

Here's a bit of back story: I've been playing DDR a *lot* lately. And by *a lot* I mean *I've spent over $100 at the arcade playing it.* So I decided to purchase a $350 dance pad for at home. (Expensive, I know, but completely worth every nickel.) Since I ordered mine after May 2015, I got a new model that has pressure plates under the arrows.

Here's the screwup: Today I attempted to perform one of the mods shown on their YouTube channel, which is to simply slide the pressure plates out of the pad, thus making it more sensitive and easier to play on. So I peel up the velcro and everything (it's military grade stuff; it doesn't stay open easily). I then proceed to slide the first couple panels out without mch of a problem. My fingers were kinda sore at that point, so I took a quick break.  
  
After going at it again for the last pressure plate, it wouldn't budge. Well, it would move side to side a small bit, but wouldn't slide toward me. So I loosen a bit more velcro and try again. Still caught on the lip of the velcro with not enough room. So I grip it as hard as I can with the sides of my index fingers (which is the only way to do it since there's not a lot of space) and just reef on it. After a bit of tugging and moving it side to side to slide it back and over the velcro, I finally get it slid out, and by that time my index fingers were tomato red and in immense pain. Turns out I have myself 3 water blisters: one on the side of each index finger, and one on the first joint on my left index finger. They're *REALLY* painful, and I half regret doing the mod (even though it feels like an actual arcade pad now.)
<bot>: I tried to take the pressure plates out of a Dance pad, ended up giving myself a total of 3 painful water blisters in inconvenient places on both index fingers.
