light and heat technology...

I know that radiancy has a spatouch and skin station for hair removal. these devices aren’t as expensive as the rest of hair removal devices. I checked and spatouch energy is 2- 7.5 J/cm2 which is kind od low. I know that skin station’s energy is 3- 10 j/cm2. I know there are people that say that skin station can give you nice results after 10-15 treatments witch touch up twice a year to have a hair free skin.They usually preffer skin station over spatouch. I just found out that radiancy had made a new LUA lamps for spatouch that double the energy output which would means that in case of spatouch the energy could go as high as 15 joules/cm2 which is even more than skin station. That could really give some good results. Light energy fluence range in both these devices is the same (400-1200 nanometers ).
anybody here used or have a spatouch with new lua lamps and could tell me if the results have been better?
