I hired this A/V installer to set up outdoor speakers around my backyard, and the whole experience…read morewas great. Gaston was very knowledgeable and helped me think through the overall layout, wiring plan, and speaker placement in a way that actually made sense for the space. He clearly knew the products, the acoustics, and how to get the most out of the system. The installation itself was smooth, efficient, and clean. He double-checked every zone to make sure the levels were balanced and the coverage felt even across the yard. Pricing was fair, communication was straightforward, and the final result feels like a major upgrade to the backyard.

Brian of Circuit Genius is a true perfectionist. He is honest and detail oriented. His word is…read morehis bond and we were fortunate enough to have crossed paths with him. We live in the South Bay in house that was built in 1921 with lath and plaster so getting good WiFi is not easy. Brian spent a few hours assessing our entire house, Sonos system and TV's. He provided a thorough, detailed proposal that addressed our needs. He did not try to nickel and dime us or oversell as others tried to do. Brian goes above and beyond (went to Home Depot to buy mat black paint to hide marks behind the media room TV). The 4 people who work for him are impeccable and care about the job being done beautifully. We are so appreciative of his work and follow through. Brian came back twice to troubleshoot a technical challenge from old equipment, at no charge because he insisted the entire system work perfectly. Read the many 5 star reviews of Circuit Genius over the past 7 years, which are spot on- so very happy that we did.

UPDATE: THIS CONTRACTOR'S LICENSE IS NOW SUSPENDED DUE TO REFUSAL TO PAY A COURT ORDERED…read moreJUDGEMENT. My initial review stated that I was forced to file a lawsuit against Brian Staller / Circuit Genius (legally known as: Performance Telecomm) for breach of contract. The matter is now permanently settled by the court. After the vendor filed an appeal, the Los Angeles Superior Court ruled in my favor and found Circuit Genius / Performance Telecomm liable for breach of contract. Owner Brian Staller calls this a "frivolous lawsuit" in his response to my initial review, but the facts prove otherwise. In his response to my first post, Brian called the lawsuit "bananas-level false" and "frivolous." The fact that I won a judgment against this company not once, but twice--once at trial and again on appeal--means that two judges ruled in my favor, finding Circuit Genius / Performance Telecomm in breach of contract. The court's decision validated the vendor's refusal to honor two key contractual agreements: 1. The Refund Scam: The vendor refused to process an agreed-upon refund for a Yamaha receiver (which the contract stated had "No restock fee if not wanted"). Instead, he attempted to coerce me into a "settlement" that required me to sign a document agreeing to no online reviews, legal proceedings, chargeback attempts or warranty support for work done. 2. Deceptive Practices: After agreeing in writing to return to my home and install a network rack at "no extra charge," he later refused to do so unless I paid a new 2-hour service minimum. He then withheld equipment that I had already paid for and refused to refund the cost of that equipment. **This Contractor is now a Regulatory Liability** More than six months after the final judgment, Brian Staller / Circuit Genius / Performance Telecomm has refused to pay the court-ordered debt. His failure to comply with the judgment has resulted in severe disciplinary action: 1. License Suspension: The Contractors State License Board (CSLB), has suspended his license for failure to comply with an outstanding civil judgment. (See CSLB Record for Performance Telecomm; License 117708). 2. Business Lien: I have filed a lien against this business to attempt to enforce the judgement owed (See State of California Notice of Judgement Lien; File No: U250127585224). This business employs deceptive practices and does not honor contractual agreements. Brian is desperate to get 5-star reviews and refuses to accept anything less even if it means bullying and using intimidation tactics with his customers. A business that ignores its legal obligations, has a lien against it, and has its state license suspended should be a major red flag to anyone reading this. Do not put yourself through a lengthy legal ordeal with this vendor. Proceed with extreme caution.

Zack at Mount Up was professional, fair priced, and delivered on what he promised…read more I had a new 65" TV that needed to replace an old TV that was mounted on a Mantle Mount. I was actually going to have another company, David AV Installations, handle the job. But that company was the complete opposite of Zack. They were unprofessional, rude, did not arrive on time, and the kicker - showed up and decided not to do the job. Zack agreed to come on short notice the next morning. He arrived on time and got to work. He was careful with the TV (given how delicate OLED screens are), and ultimately got it installed exactly where it needed to be. Thank you Zack for delivering quality TV mounting services and accommodating our tight schedule.
