Dave was great! I had him come to my house and connect my sonos system with the rest of my 1990 stereo system and set up differ t zones around my house, garage , backyard etc. I could have done this myself but it may have taken me 2 days with the new universal remote etc. Man was this money well spent and Dave was very efficient in getting all this hooked up- PC HELP FORCE is not just for PC's he does everything electronic and I highly recommend!
