A recent encounter with YARONGTECH left me feeling let down and frustrated. They sold me a home security system, but when it arrived, it was incomplete and the components that were included were of a bad quality. My attempts to get in touch with their customer support team were met with responses that were not helpful, and they did not seem motivated to help me resolve the problem. My entire experience has left a sour taste in my mouth, and as a result, I am unable to recommend YARONGTECH to anyone.
