To me one of the most important questions: which timings are available between 0.1 and 0.3 secs? Steps of 1/10th secs, like the older Spectrum, steps of 1/100th secs or something else?
The latter would give You a much better flexibility to adapt between sensation and healing. (I have been in discussion with Skip on that...)
What about heating patterns? Are thermolysis units producing effective heating patterns to cover sufficient tissue in the follicles? Is the industry too focused on painless sensations and rapid healing at expense of poor heating patters that don't destroy follicles in least possible clearances?
