I have an aluminium Benro A-058-M8. This is their 0-series classic travel tripod. I also have a Gitzo 1542T.
From the build quality point of view Benro is really nice. The twist locks are smooth and lock positively. The metal parts are also high quality. For the amount of money I paid (around $80 about three years ago) it is an absolute bargain. That being said the Gitzo is slightly better in all aspects, but with a steep price. Bottom line is if you have the money or are in need of the best tested tripods in the world, go for the Gitzo or RRS. If you are on a budget, the Benro's will give you 90% of what the more expensive brands will, at around 1/2 or less of the price.
