They're good tires. Often they flat more than other tires due to propensity for wider supple tires to take and hold glass that works through the tread into the tube over many rides.

The hyperbolic marketing and inviolable nature of their performance due to the argumentum ad verecundiam based discourse with company representative(s) is a turn off to many. As is the price. There are equal and much better tires from competing brands in the narrower 700c widths up to 32mm. They are without peer for 650b sizes as well as all sizes above 32mm for slick tires. Many of their tire models are narrower than advertised and it is a toss-up if they will grow through use. There knobbie tires are much more down market than their road slicks. Little reason to choose Compass knobbie tires when there are much better rolling and much better engineered tires from other companies.

The prior development tires, produced by Panaracer as well but labeled as Grand Bois, feature thicker tread with only minimal weight increase for the same rolling performance and true-to width size. Grand Bois tires tend to last 25-33% longer than Compass tires and are more true to size.
