Bikeradar had a 4.5 star review up saying they were powerful, great modulation, no fade etc which suddenly changed to a 3 star review recently.
Personally been very happy with the set I bought last year. They can lock up either wheel easily so more than enough oomph, are pretty controllable and once set up have been fit and forget.
The pads do run pretty close to the disc which I like as it means instant bite but it does also mean they can be a little noisy when wet or gritty.
I’d buy another set quite happily (had I had more funds available at the time I would have bought R1’s)
