Pop & Lock Tailgate lock

Just wondering if anyone has used/installed one of these Pop & Lock Tailgate locks and maybe get some feedback on them. I just bought a Silverado and would like to put a tailgate lock on it. Is this thing worth the time and money?

Thanks

With a bed cover it is a great idea, adds a bit of security, but it will only stop the honest thieves, If they want in, they will get in.
