I have never used this product as it is fairly new to the market. I read about it in Trailer Boat Magazine and it looks like it could be a very nice addition to a safety chain and also looks like a very effect anti-theft device. :thumbsup: They cost $49.99 for the dual arm and $39.99 for the single arm models. Might be worth a looksee and addition to your towing rig.
