Very smooth and consistent pressure evenly applied to the full circumference due to it's design. I use a little Park Tools SAC-2 Supergrip on the seatpost for a rock solid hold.

The cheap clamp that came with my bike put too much focused pressure at the very top of my seat tube that prevented my dropper post from operating smoothly. I could only put 4.5 nM of force on the clamp before it caused problems with the dropper function but the seat post would still slip in the tube.

Suspecting that the clamp was the issue I looked for replacements that do a better job distributing the force. The BikeYoke Squeezy appeared to be a good candidate but price and availability was a problem.

I've had good experiences with Wolf Tooth so I sent them a note asking about the dimensions of this clamp specifically the lip at the very top that prevents the clamp from sliding down the tube. They answered promptly and the dimensions looked good. The price was much better than BikeYoke plus it's a US company so I gave it a try.

The clamp works perfectly I can crank it down to 6+ nM. The post doesn't slip anymore and the dropper functions flawlessly. It's VERY light and looks great.;
