I've been using the Giottos VGRN Tripod on a couple of trips recently and found it to be a very capable tripod. It is much lighter and less substantial than my usual Gitzo but it closes down to appx. half the height and weighs 3/4 KG less.
I chose this tripod due to it's lightweight, compact closed height (for packing into a suitcase) and it's decent height when opened up.
It has 4-section legs which obviously get a little thin at the base and bow slightly under weight but the carbon fibre seems to work well to dampen any movement. There is a hook on the base of the centre column that allows additional weight (a camera rucksack for instance) to be attached which helps stabalise.
I took a long exposure shot on the beach in St Lucia (appx. 80 seconds) the tripod did an exceptional job.
Overall I recommend this for an affordable option for a second tripod (or even primary) for most users of cameras up to around D800 with 70-200 f2.8 which is a substantial weight.
I have recently purchased a Fuji XE-2 for my travel camera and have been testing this camera out with the Giottos VGRN 8255. The picture below was taken recently in London and is a 4 minute exposure. The Giottos handled this scenario perfectly with no problems at all with movement during the shot.
I had a RRS BH30 that I am using instead of the supplied Giottos ball head. I prefer the arca swiss style camera plates.
