• ويستخدم النظام محركات ذكية ذات دوائر مراقبة مدمجة بدلاً من أن يتطلب سائقاً منفصلاً، مما يجعلها وحدات مراقبة ذاتية الاحتكام قادرة على تسجيل وتكرار الحركات بدقة.
• وأظهرت وحدات الخفض المبكر فقداناً في المعايرة عندما حُدد العدسة بحيث لا نهاية لها، مما يتطلب إعادة التأهيل بعد فقدان السلطة، أو إغلاق المتحكم، أو التأثير المادي.
• The initial single-knob controller could only operate one function at a time across three motors, though developers acknowledged demand for concur multi-channel control.
• The focus knob required multiple rotations to traverse the full lens range from close focus to infinity.
• Promised improvements included a larger focus knob with single-revolution full-throw capability, dedicated three-channel controller below two thousand dollars with features comparable to motion control systems, fixed calibration stability, and wireless functionality.
• Motors feature strong output despite small size and use an inverted M-one style quick-disconnect connector.
• The system was originally planned as a RED camera accessory before the developers pursued a universal independent product.
• Operating frequency of 2.4 GHz may potentially interfere with some wireless video transmission systems.

• The discussion covers only early 2008 prototypes shown at a trade show, not production units.
• Described problems were observed during brief five-minute booth demonstrations and may have been corrected in final versions.
• The promised pro controller and wireless features mentioned as future developments were not yet available for testing.
• No field testing data was provided by working focus pullers.
• Compatibility with other follow focus motor systems was not supported by the design architecture.
