Easy installation if you have the space, I also added a relay just in case: the fuse (10A) had no issues - the horns together draw about 7A - but for the protection of the switch from higher current. Clearly a stronger sound than the factory horn. I still need to see its durability over time. The downside compared to the factory one is the two open channels of the "snails" where it's not good for water to enter (from rain/water on the road or during washing), that's why 4 stars instead of 5.
