While I'm at it, I found and summarized actual reviews from Reddit.

For those who used FlexStrike at EVO, what was your actual experience like?
I'm especially curious about the mechanical buttons and joystick feel.

Positive Opinions

• “Honestly, I liked it.”

• “The shape and form factor were really good.”

• “The lever was excellent.”

• “The feeling of resting my hands on it was surprisingly comfortable. Both the lever and button sides were comfortable.”

• “The stick felt responsive, and the clicking sound when moving it was satisfying.”

• “The flat, glossy feel on top of the buttons was nice when my fingers touched them.”

• “The buttons were very quiet, almost no sound was heard when pressing them.”

• “I also used it at EVO, and it was surprisingly quiet. I was very satisfied.”

• “I was planning to buy it for the wireless functionality, but now I'm convinced it's what I was looking for in terms of noise and ergonomics.”

• “I like the smoothness of the DualSense actuators, so honestly, that's exactly what I was expecting.”

• “A clicky stick with membrane buttons, no joke, it's my dream combination.”

• “Although I'm worried about the buttons, the biggest reason I want to buy this fightstick is the ability to swap restrictor gates on the fly. That's a huge advantage for me.”

• “The only complaint might be that it can't be modified, but I might actually buy it.”
  
  Negative Opinions

  • “The buttons have mixed reviews.”

  • “The buttons felt very mushy.”

  • “There was no feedback like when pressing Sanwa or Seimitsu buttons.”

  • “The lever felt okay, but the buttons felt mushy and strange, with a lot of travel distance.”

  • “It feels like enlarged PS5 controller buttons.”

  • “Imagine DualSense buttons scaled up to fightstick button size, and you'll get the idea.”

  • “The lever was excellent, but the buttons were terrible.”

  • “Make sure to check it out in person before buying. I canceled all my purchase plans after trying TOKON with this.”

  • “Thanks for sharing. I'll cancel my pre-order too. The buttons were my biggest concern.”

  • “Reading comments about the buttons being mushy, I suspect they're using membranes commonly found in cheap sticks from the early 2000s. If that's the case, it's truly disappointing.”

  • “They should have just used full-size MX switches and made the buttons hot-swappable, like everyone else does.”

  • “It's not customizable. Only the restrictor gate can be changed.”

  • “Then replacing the stick when it breaks would be a hassle.”

  • “It might be the first lever to experience stick drift.”

  • “Isn't it too light when placed on the lap, causing issues?”

  • “This is also very thin. If the lever could be modified to be detachable, it would be an excellent portable stick.”
