March 2011 UPDATE:
Effective March 2011, Evolution Hair Centers will no longer carry the Spencer Forrest X5 Laser.
1. Due to the failure of the Spencer Forrest company to gain a the FDA 510K market clearance after clinical trials,
2. lack of customer service and support,
3. and new and more effective laser to hit the USA market, I have dropped Spencer Forrest from our company.
As of 2011, the iGrow Laser is my affordable homecare laser choice. The THL-1 in my opinion is still superior. But if you cannot spend $2000 on a THL-1 Laser, I would highly recommend the iGrow Laser Device.
