Works very good and is silent but wish it had a mounting bracket,but so far the 2 sided tape is holding up. Had to mount it above ceiling tile on the drywall

Perfect for my app. Good price.

Minimum space-Maximum utility. Excellent quality and value.

I have installed this relay but unfortunately I have yet to complete the system in which it was installed. Though I can't comment on its operation, I can say that I am very pleased with my experiences with Smarthome.com. This relay is not the first product I've ordered from Smarthome.com nor will it be the last.

Good quality relay. Used it to drive a high-power alarm siren. Smarthome is a reliable vendor.

Low cost and small size. Works great.

This ELK-912 Relay is one little inexpensive yet versatile product. I needed to connect my GE Concord 4 Security Control Panel to Lutron VCRX Visor Control Receiver that handles the program for flashing exterior lights and locking on interior lights while alarm is sounding. GE Concord has not supported driver for Lutron. An electrical engineer on the Lutron Radio RA2 discussion site told me about his relay. He is awesome and so is the relay. That was the final step and setting up my Lutron system to take advantage of all its features. The ELK-912 at $8.50 is awesome device.

Met my requirements perfectly. Very well constructed.

Did the job.

Works as expected. Instructions are a bit hard to understand if you're not familiar with electronics.
