Cheap and effective at first.

But be aware:
Columns wrong slide: You have to be really flat on the entire sole to go down.
Curiously columns better glide climb: the router back too often alone, even tightened; it must force all the way to preserve the depth.
The small LED to see what we do does not work (1yr).

So yes it works fine.

Yes I'll change and yet I'm a pro who uses 24/24.
