Overview

• A manufacturing tolerance made the Killswitch case’s retaining lip 0.12 mm thicker than planned, filling Nintendo’s designed air gap and increasing mechanical leverage that led Joy-Con detachments
• Facing backlash for blaming users’ “unnatural” grips and analogizing the issue to Mentos in Diet Coke, CEO Adam Ijaz admitted the company’s initial response was “spectacularly terrible”
• Dbrand has pledged to ship free replacement Joy-Con grips to every purchaser, regardless of whether they reported detachment problems
• Engineering teams are pursuing two fixes: a thinner-lip variant slated for mid-July production and a more ambitious “Holy Grail” redesign undergoing mass-production trials by July 10, 2025
• Reports showed players with smaller hands or those holding the console solely by the Joy-Cons were most affected, prompting revised tolerance and inspection guidelines
