Mike O'Brien

American YouTuber, Engineer, and Digital Marketer

You might have found me via my tech review channel on YouTube, or perhaps through one of my other channels. I have been making YouTube channels since 2017 and focusing relentlessly on improving the quality of my content. I did not always plan to be a YouTuber though. 



In late 2017, I was in my senior year of college. I was pursuing simultaneous degrees in mechanical engineering and physics but I decided to start a YouTube channel on the side. Originally geared toward engineering students, my channel reached a few thousand subscribers by the first summer. After graduation, content about test-taking tips became much less interesting and I adjusted my trajectory to begin focusing more on tech. I have always loved learning about the latest product innovations and analyzing the newest phones, earbuds, watches, tablets, and laptops.  I have since ranked among the top in YouTube searches for “best earbuds,” “best smartwatches,” “best eBikes,” and much more. After just over a year of working as a new product development engineer at a major smart home company, my channel was large enough to sustain my lifestyle and I left my job. Over the years, I continued to expand my gear library, improve my video quality, and enhance the video style. The channel is still young, and I am very excited to continue to expand the horizons of the brand.
