Well it's probably heavier (I haven't checked the weight) and Manfrotto tripods/monopods tend to be built like battleships. It hasn't got a fluid head though that's more useful for video. Personally I don'y like the twist locks, they're not positive enough
Why get this over something like the Zomei Q666?
as already said - its NOT higher in the rest of uk there are other retailers with the same or lower what does it matter if they only have one? how many do you want?
It is a typical price for Amazon, but they 'say' they've only got one, and I'm in the habit of looking at the other Amazons, it, fr, ge etc and where you can find this combination, it's a lot higher. And it's a lot higher in the rest of the UK
Same price at WEX... https://www.wexphotovideo.com/manfrotto-xpro-video-5-section-aluminium-monopod-1609550/
