My roomate and I live in an apartment building and there have been warning lately about safety and breakins and not leaving your home or car unlocked. We wanted to install some deadbolts because we both have vaulables we dont want to take the chance losing. So we found TOP 10 on yellow pages and made an appointment. The guy came over and installed a nice big dead bolt for us. I felt safe leaving the house knowing no one was getting past that thing.
