It was my first time ever with any kind of slider, so my moves were not as smooth as they should be. However, I am very happy with my newly purchased SlideKamera S-980. Build quality is fantastic, movement is smooth, and the price amazing. Its only disadvantage is weight. You need a really sturdy tripod. I'm using Hama Compact Traveller Pro rated for 10KG of load, with S-980, Velbon PH-368 Fluid Head (very light), and Canon EOS 7D (with 18-135mm lens) - its legs flexed substantially, you could tell that if you add 1-2KG of extra load damage could be permanent - just keep that in mind.
