I have spent the last several weeks researching laser caps and still cannot decide on which one to purchase. Of all the caps I researched, the three that looked the best to me and cost under $2,000 are the Hairmax Powerflex 272 (cost $1,650 with coupon), Kiierr 272 (cost $800) and Illumiflow 272 (cost $800). Has anyone purchased any of these laser caps? The Hairmax looks more comfortable to wear then the other two devices and has medical grade lasers, but cost double the price. Also, Hairmax has been around for a long time compared to Kiierr and Illumiflow. The reviews for each device are 4 out of 5. I am skepticle if these reviews are legitimate and do not want to buy the wrong product.
