I love the build of the pedals, they're fully metal and rather high quality, however the height adjustment isn't tool-less and will misalign over time if the nuts aren't properly tightened.
My largest complain is the calibration software, it's a confusing and clunky piece of steaming dodo that you are forced to use if you adjust the height of the pedals. There are multiple axis' listed for the pedals... I don't know how that is possible but it is. Most the of extra axis' can be disabled however you'll have to tweak some variables to calibrate correctly. I had to read the documentation to figure out what this unintuitive mess was.
I personally disabled all axis' except the "Rot X" and "D_MaRS". Then if you intend to lower the pedal height, you will need to increase a "D_MaRS" variable called "MPL" to at least 10. Then going to the tools and running auto calibration.
Ultimately these are great pedals if you are willing to look past the software, I would prefer some heavier springs being included, but that's rather minor. VKB really needs to improve this software to have correct variables already set so auto calibration works out of the box.
