Paid for itself the 1st time
We had our laser light stolen, from our front lawn area...not more than 2 days after putting it out. Our daughter was heartbroken. I didn't even know there was a such a thing as a security cable. We ordered another SL-33 and the security set. The cable is about 25 feet long, includes two locks and a key. Straight forward to connect to the fixture, and we tethered it around a tree nearby. Somebody actually tried to run off with the light the next day, and didn't get very far. The surveillance footage showed them picking it up, walking away and the tethered cable yanked it our of their hands. Guess they didn't know we had locked it. That was a few weeks ago and no issues since. The quality of the wire leader cable is good, and master locks. If you live in a high theft area, or unsure...and don't want someone walking away with a hundred dollar light, you need to get this!
