This tripod was my first heavy-duty one, replacing an old lightweight one.
I find the tripod easy to use. The legs extend easily, and the locks hold very firmly. So far, I have used this tripod standing on concrete, wet sand, and grass; it has performed admirably, and has allowed me to get some good shots. Even in quite windy conditions, the tripod has remained very stable. I have only used it in the basic layout, and have yet to experiment with opening the legs wider, angling the centre post or inverting it.
While the tripod is good, the acccompanying head is a disappointment. The quick-release D ring in the back is often a bit too quick to release. Unless you are using the camera in landscape mode, I find the D-ring will not hold the camera in place (particularly if using a zoom lens). If you do get the ring tightened enough to stay, the D-ring will then not return to the flat position, making it impossible to attach the plate to the tripod. My suggestion is to ignore the folding D-ring and take a hefty screwdriver with you instead - it save you mangling the edges of your coins!
Also, be aware that the matching Giotto's bag will hold the tripod, but will only take the head if you unscrew one of the handles on the head, which adds to the time needed to set it up.
Overall, a reasonable tripod and head, but with definite room for improvement.
