FS Locks has a nice looking website, and what appear to be pretty reasonable prices--but don't be fooled. When you call to get that decently priced lock, they'll tell you that they have a new model--but it's twice as much. When you give them the money for the lock--they'll take it, and never send the lock.
Check out their rating on the BBB--a D. Call them and try to get someone to help you with an order--get this, they'll tell you that they only have people to TAKE orders--nobody to do anything else. You can't get a supervisor. They are the worst company I have EVER dealt with. Run away. Fast.
Oh, and you can check with the California Attorney general as well, if the BBB doesn't do it for you. Be warned--these people have an internet scam. They are not a reputable company.
