I was skeptical about the CES Max at first. My prior experience with cranial electrotherapy stimulation (CES) came from a high-end device at a neurology clinic, which delivered immediate, measurable results for insomnia and anxiety—but with a $600+ price tag. When a friend with severe vertigo was desperate for relief, I decided to take a chance on the CES Max, despite the limited reviews and a website that didn’t inspire much confidence.
I’m so glad I gave it a try. The CES Max is effective for relaxation and stress relief, and my friend saw noticeable improvements in their vertigo symptoms. While it’s not as refined as the expensive devices (the electrode clips can occasionally cause a sharp zapping sensation), it’s a functional and affordable alternative.
What impressed me most was the customer service. When my device stopped working after a few months, Zen of Sleep replaced it promptly after I sent a video of the issue. Their responsiveness gave me confidence in both the product and the company.
Although I usually stick to science-backed products, my experience with the CES Max proved it’s worth trying—even with limited research. If you’re curious about CES but not ready to invest in a high-end device, the CES Max is a reliable and budget-friendly option with excellent customer support.
