    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.

    Gbit Tech did an amazing job with our home low-voltage / networking install. Golan and his team ran…read morehigh-speed networking throughout the house, wired up multiple ceiling access points, installed a fully wired security camera system, and mounted a couple TVs with clean in-wall wiring. Everything was routed back to a central rack in the basement, and the work was neat, organized, and actually tested. Not just "looks good," but properly finished. I also came in with a lot of specific requirements and definitely took us down a few rabbit holes. Golan was totally game to go there with me and think through the weird edge cases, but when things started getting a little too "okay, this is getting ridiculous," he'd pull me back and steer me toward a smarter, cleaner solution. I genuinely appreciated that. What really stood out is it never felt like he was trying to upsell me. Just honest advice, solid recommendations, and a clear priority on making sure I was happy with the end result. Professional, responsive, and detail-oriented. I'd hire them again in a heartbeat.

    Hired Golan to install a new Ubiquiti system with Unifi G6 cameras and I have to say Golan knows…read morehis stuff! He was so patient with me during our first meeting from answering all my questions to helping me make the right decisions on equipment needs. On the day of install, Golan and his team were fantastic. They worked carefully and with respect, something which can be a hit or miss with contractors. Golan consistently went above and beyond on answering questions and finding solutions to unique challenges. He's also as picky as I am on making sure everything is perfect! Golan is truly an artist when it comes to making sure your rack looks clean and organized. Don't hesitant to hire him!

    I am an artist in Los Angeles and was invited to place several works of my original art on…read moreconsignment by Jeremy Scott who represented that he was a partner with Chameleon in launching a private clubhouse at Chameleon's Pontius Avenue address. Scott clearly was in the process of doing a major high end remodeling of the building's upstair's space and it appeared to be only a few weeks away from completion.Scott asked me to bring my art work to the location and had offered to custom frame my art to fit the decor. Additionally, he asked me to create a series of 8 original golf paintings as "golf" was the theme of the clubhouse they were building. From that point on, everything was a total fiasco. Not only did the project never get finished or open, I had to beg for months to get my art work returned to me, only to find that Scott and Chameleon both claimed they could not find one of my paintings, worth several thousand dollars. Scott rarely returns phone calls or text messages and seems to have a penchant for misrepresenting things and making false promises and claims. These are very unprofessional and dishonest people to work with. I did everything I promised to do- I provide thousands of dollars of art on consignment, custom painted an entire series of golf paintings as exclusive decor for their club and even more- and they couldn't even return to me all of my art. Of course, they did not even frame anything, so in addition to making me suffer losses, they incurred zero expenses.
