Fills my expectations ...

I wanted to improve my macro shots. This is done with the Super Mag Slider. I can easily and precisely position my EOS 5D Mark II both laterally and in the axis of shooting. Very good build quality, no play in the bearings, not very heavy. No big flaw. The only complaint I can make it, concerns the handles that should have been deported more for better grip. But nothing serious ...
For Amazon, as usual as perfect. Order, time, delivery, perfect.
