Keeps well until about 2 kg, above moderate. Ball not quite round which no longer bothers with heavy equipment. My Eos with Zeiss lens and 2.7 kg in weight fast is the ball head its limits. The screws for clamping friction and are not secured against unscrewing, thus possibly from dropping. Who thus hits the road should pay attention to this. Very good backlash release plate with soft rubber lining. These snaps very well and is well protected against accidental disengage.
Conclusion: Good ball head for travel and normal DSLR equipment at a fair price. But who is traveling with the slightly heavier Photography Equipment should look for a larger ball head.
