I have one of the original 4 section CT-3402 tripods from them, bought about 2 1/2 years ago from their ebay shop, which used to be the only way to buy them then.
Consequently I was stung for an extra £30 import tax on top of the £130 price tag. The older ones had plastic leg locking collars, which some expressed concerns about at the time, but I've read lots of online reviews and couldn't find anyone who'd had a problem with them. Now the collars are made of metal, amd the tripods are available direct from the importer in the UK. They also seem to be lighter too.
Mine is lighter in weight than my Manfrotto 055MFV (about 1.4kg compared to around 1.9kg for legs only), but not as tall and less sturdy too. I'd guess it's probably more equvalent to the smaller 190 series. I use mine only occasionally, especially when doing more walking around when I don't want to carry the extra weight. I prefer it without the optional centre column which is a strange design with an extra extending section inside, preferring instead to use the head attached to the flat plate that sits on top of the legs. This was included in the price. Of course, this means that the max height is only around 1.2 metres when used this way.
It seems that specs are slightly different on the latest models, and they look to be improved to my eyes, though to get an equivalent to either the Manfrotto 055 or larger Gitzos I think you'd need to go for one of the larger models than the CT-3402 (or similar models). They seem to be a decent company to deal with, and the tripods are nicely finished and well made, just not all that cheap anymore compared to an equivalent model from Manfrotto. I've heard many reports that they are 90% the quality of a Gitzo at half the price. I can't speak from experience, but if the larger models are proportionately as sturdy for their size and weight compared to mine, then probably this isn't far from the truth.
