This review is focused only on one aspect: installation. I gave 4 of 5 stars for overall, but 5 stars for the quality of service, specifically, the installation. I would like to compliment our two installers, Zhongkui Lin and his assistant, Alex. Both men went about their business in very professional and friendly manner. Mr. Lin was very thorough and courteous in his explanations. In particular his personal tutorial of the remote was an education.
