I've made up my mind and i'm going to invest in a lasercomb but I can't afford it unless I get it discounted, or on ebay. My question is, are there alot of little parts in the lasercomb that can malfunction thereby making buying one on ebay a decent gamble. Or are they pretty straightforward and if someone claims it works, chances are it does? I figure most of the online sellers are just men who tried it and gave it up because there hairloss was to severe, nothing should be wrong with it if this is the case. All input is appriciated, thanks.
