The slider is delivered! I expected a big box but this was not very impressive. That's a good thing, though, because smaller means less weight and easy carrying.
First impression: very solid. This thing will not bend easily so a camera like an EX1r with monitor, mics etc should be no problem. It's a simple piece of gear: screw the feet on and it's ready to go. Well, in my case I had to adjust the bearings because out of the box they were a little tight. When placing on a tripod it obviously has to be perfectly balanced. And you need to really lock down the head because it will tilt under the weight of the camera. I had a hard time locking down my Manfrotto 503 head. If it's not rock solid, you will get camera shake, particularly when you reach the end of the slider. A DSLR like the 550D on the slider with one tripod is manageable, even though it didn't feel 100% With a bigger or heavier camera, I would recommend 2 tripods or supports for best results. Especially when shooting tele.
I tried placing the slider vertically but had a very hard time to go upwards smoothly. Down was easier, for obvious reasons, but you need a good monitoring device to know what you're doing. And 4 hands. I'm not sure I'll use the vertical option very much.
All in all, this is a very tight little slider. It's definitely worth the money and will greatly increase your painter's palette, so to speak. You won't regret this purchase.
