Dave was prompt in contacting me and in following up.  He was friendly and had some great ideas on retrofitting my home for a security system.  I found him trustworthy, honest and helpful.  He has followed up with me after the install to see if I have any questions or concerns.  I like the fact that he is local, doesn't 'farm out' his work, and is the go-to person should any problems arise.  I would definitely recommend DAVs Amusements.
