The KCT-11BB supersedes all other KCT-11RS, KCT-11R, and KCT-11 spinning turbo keychains. This has all new internals. Complete redesign that includes twin shield chrome steel ball bearings. All KCT-11BB's are certified to spin at minimum of 35,000 RPMs @ 3PSI. Some can achieve up to 55,000 RPMS with human power. This video is product test footage at operational limits, theoretical design limits, and grossly exceeding limits in attempt to induce catastrophic impeller failure.
