K&M 12195

The stand has the usual high standard of craftsmanship one would expect from K&M. It's incredibly sturdy and perfect for my setup. Happy customer.
Pros -
Many heights and angles to choose from
Good weight, doesn't wobble if typing on the laptop
Well built
Looks great
Cons
At low angles it can be hard to fit anything onto the base underneath due to the angle and the mechanism under the laptop table. (Not an issue if using a wireless keyboard)

You should not forget that two knobs that fix the angles/position, are not friction-based but toothed. If you set the angles – it won’t go anywhere under the weight, ever.

I bought it after returning 12190 (which was also great, but not flexible enough and could not get lower than some fixed heigh – which was too high for me), and cannot be more happy.

A very solid piece. Very well built.
