I must say that I was uncomfortable with the LockZilla Thread. This product has been out there forever. If there was any serious issue with it killing batteries I would assume that the person who would have noticed it first would the guy who designed it. No disrespect to the poster of the question but Bob's products have stood the test of time. I personally think that the thread was unintentional in it's message that LockZilla's are to be avoided due to power draw. So let's make this very clear.....any newbies reading this....LOCKZILLA is awesome and is well worth your investment!!! Installed mine over the weekend including new solenoids. I'm now100% confident in my locking system as well as getting a 5 year warranty with the complete kit from Rob. What more could you ask for?..........How about Launchers!!!!!! Can't wait.
