As someone who has tried the leading brand Biomat and this HealthyLine mat, I would like to give a comparison for anyone who is interested. I would compare this model to the Profession Biomat 7000MX. They are roughly the same size and aimed at the same target audience. Having used both I have to say that I think the TAO mat by HealthyLine is a better value buy. They are both great gemstone heat therapy mats, don't get me wrong. The Biomat even wins in some categories like the controller, but overall that's not the case. The Biomat is filled with amethyst gemstones. The TAO has amethyst too, but it also has tourmaline and obsidian. In my experience, a mix of stone yields better results for the way I feel. What really places the TAO mat above the Biomat is the added benefit of the pulsed electromagnetic field system. If you aren't familiar with PEMF, a PEMF device is usually more expensive than both of these products combined. Somehow HealthyLine has found a way to provide it in an affordable package and let me tell you, it works. This mat has done more for me in 3 weeks than the 7000MX did in an entire year. I have so much more energy, I actually feel lucky. If you ask me 100 times to choose between these mats I am picking the HealthyLine one every single time.
