Fischer TS-1???? 15%

Hi Folks,

Been using the TS-1 for about 3 months and seem to have a success rate of about 15%. I am a very mechancial person so I find inserting the prob easy. I have tried numerous settings. The setting that I get a good release with does not hurt. But the red marks continue to linger for 1-2 weeks. Over treating? or normal

Is the TS-1 a good unit?
