I've owned and been using these since discovering the Relax Far Infrared Sauna in Schaumberg, IL in 2006, and it is by far the most powerful and effective product I have ever used. We have both silver and black models and even my elderly parents are enjoying the positive results. I've tried other products that cost several times as much and didn't even come close to the quality and effectiveness of this one. There's a reason people are copying their products and trying to sell them on other sites, and it's because they know people will think it's a Relax brand when it isn't. If it doesn't say RELAX it isn't.
I love my Relax Sauna lamp. No bulbs to crack, base is heavy and stable, small-so truly portable, easy to store and use. I can actually feel the heat penetrating deeply which is different from other red lights. I wish it had come with more info on how to use the lamp properly for the most effective results.
My spouse & I use the sauna almost daily, Very pleased with our experience.
I recommended to my cousin & she ordered one immediately for her & her husband
