Durable
I'm using this to control a fireplace. An Ecobee uses 24V DC. The Ecobee is wired to the coil and the fireplace thermostat wiring is connected to the relay contacts. So when the ecobee gives permission, the fireplace turns on, but doesn't get 24V. Has worked perfectly for several years before needing to be replaced. Makes a noticeable quiet click when engaging.

I wouldn’t by it twice
Used this for a blow horn on a Harley-Davidson and only lasted a couple of times, maybe six beeps and it was over 🤷

Most have been good quality, last one I ordered, no operation at all
Last one of these (used in car alarms) has no contact, internally. Looks brand new, no marks on the connectors, etc., but doesn't work. At all. Disappointed in Bosch

It is a Bosch but a lot less money than other makes of dual 87 terminal relays. Great for dual auxiliary lights.
