This gimbal head probably one
"This gimbal head probably one of the most easiest to pack and carry, I got that for my 600mm f4 lens coming up, the only 2 bad things about was the head movement a bit sticky not as smooth as what I expected, so I was trying disassemble it and replace the higher quality grease, however they put some sort of superglue (either blue or red type) to every single screws, so I was having hard time to disassemble it, but thankfully since I’ve been working as mechanic for a good 15+ years, been deal with uncountable time of that kind issues, so at the ended I was able removed the whole assembly, then removed all the sticky low quality grease and putting higher grade of grease instead. Otherwise this gimbal head was well made."
