I got this tripod about a month ago and just got back with it from a trip to California. I think this tripod lived up to my expectation for a lightweight and compact tripod. A bit about the backgrounds of my gears, I have a 5D Mark II, 24-105mm f4, 16-35mm f2.8, 70-200mm f2.8 IS, all Canon's L series lenses. If you've used one you know how solid (or heavy) they can get. I used my older 486RC2 ball head with this tripod. I think in my own experience, they are all supported fine with this tripod.
I also own Manfrotto's 190XB aluminum tripod for quite a while. It is very solid but often a bit too heavy for carrying it extensively. It's also too long to put it in a carry on luggage for a flight. So I decided to get a more compact and lightweight replacement. This isn't the cheapest carbon fiber tripod I found, but I've had good experience with Manfrotto so I decided to give it a try. Weighting 2 lbs it is exactly half of my 190XB, and the folded length is also much shorter. It fits in my tiny carry on suit case (without a head) perfectly, which is very convenient for traveling. I also attached it on my backpack (Lowepro Flipside 400) and it didn't add too much weight and balance, so I'm definitely happier.
Compare to my 190XB, it does not feel quite as strong, particularly the 4th section of the legs. I would not recommend using this in a windy condition for it might wobble. But when you're looking for a compact/lightweight tripod, this is the compromise you have to make, especially for this price. It's also a bit on the short side, even for me (I'm 5'6''). But for my purpose, I will keep both of them and use them under different situation.
Overall, I would recommend this for people who want a compact/lightweight and yet still quite sturdy tripod.
