Customer in Fremont, California

 DS4Y installed my cable lines to 3 rooms. We had abandoned the old ones during a remodel. The did a good job and I am happy withy the results. They went above and beyond to help me with a Nest connection problem (I didnt hire them to do this) and texted me in the following days to share youtube videos and links to support in order to help me solve the problem. They are interested in learning new technology and willing to share their expertise to problem solve. I would contact DS4Y again if needed and trust they would do a great job!
