Easy installation and good cooling, if it works I have a defective relay. I've installed other relays alongside this one and they've been fine, so it's not the weather or the environment. I swapped the relay for a better one and had no problems. I've ridden about 10,000 miles in various driving conditions as well as off-road since installation, apart from an issue with the relay it has worked well to keep the engine cold. It's very loud, making it difficult to listen in the car or at the bank.
