This relay is very easy to install. The hand/auto feature is required by most engineers in the plan and spec world and this relay fits the job. The LED is an easy way for the customer to see "on" status. The quick release base din rail feature allows for easy and quick installation or retrofit.
Pros: Good value
Cons: made in china
Yes, I recommend this product.

I use these relays on every BAS control job i design and install. I am partial to them because of the added features such as the manual ON function for testing and the LED indicator. I have installed hundreds of magnecraft relays and have yet to receive a bad one. Good quality control from the factory.
Pros: Good value, reliable
Cons: not always in stock (plan ahead)
Yes, I recommend this product.
