Buyers should prioritize load-bearing capacity, ensuring the motor can handle the weight of the display item (e.g., crystal, jewelry, or heavy glass) without stuttering. Look for dual power supply options (AC adapter and battery) for flexibility. The LED configuration is also critical; high-quality bases feature SMD LEDs for brightness and longevity, with options for multi-color RGB cycling or steady warm/cool white light. Additionally, verify the rotation speed (RPM)—a smooth, slow rotation (approx. 1-3 RPM) is generally preferred for luxury displays.
