    I couldn’t be honest.

    "This board failed me, so I cannot vouch for the wellness, but what I can vouch for is RDQ’s customer service joint with HappyModels. Everything was sorted out, love doing business with these guys. I wish I could give it five stars, but not RDQ’s problem."

    — Stephan B. (3/5)

    "Of course I noticed after applying my first bit of solder but it was missing a component. Never got to use and never got a resolution through RDQ or Happymodel. Always remember to check before you solder."

    — Brandon (3/5)

    Paired nicely with fractal f65,
