Just guessing that extra precautions may well be being taken . Having thought about it a bit , I ' m probably wrong . I haven ' t read a single report of anyone getting into problems due to overheating ever and by problems , I mean fireexplosionpermanent damage to phoneextreme wear and tear . None of that has happened so far , so it ' s pretty safe to say that it ' s as safe as it can be . Unless you have a note 7 . <| sep |> Pump dump . Buy with fear and caution . <| sep |> I found it on a posted ad nearby a few months back . I live in new York . Guy said it was all from a haul he did back in 2009 . I actually bought a BVM and this 20 PVM and another 14 PVM cube sort of came with it . Guy wanted them out of there haha . The bvm is alot better but I ' m waiting to have an rgb system . I have the n 64 hooked up through s video on this PVM !
