I'm not one to typically write reviews but I had to for this product. HFL Blood Flow Optimizer has changed my life. I received it as a gift and at first was skeptical, but after only 2 weeks of use, I've already noticed a difference. My legs feel much better and usually don't even give me issues unless I walk around for too long without sitting. My circulation has improved and one thing that was interesting is that my skin doesn't get as cold as it used to.
I've never been one to take good care of my health and I'm so glad that I was introduced to this product because it has honestly changed my life. I would highly recommend it to anyone who is looking for an improvement in their circulation or just wants to take better care of their health in general. I'm so happy with this product and the results that I've seen from it.
