Installed Hi-Q brake pads over two years ago. I ran over more than 20 thousand km during that time, but the pads have not yet given up. When I bought it, I was afraid that it would be a fake, but nothing happened. Ordered online for delivery. Spare parts have an adequate cost and are distinguished by high braking efficiency. Never heard a squeak or hum. I will buy these for the next MOT, which will probably come in a couple of months, because I travel often and a lot. As for the shortcomings, I think that they are too soft, because a lot of dust is formed. But the brake disc wears out less, which is very good.
