Query: Hot item

When I first received the trimmer there was a lot of buzzing and ratteling. I returned it.2nd trimmer. Switch was BAD, thing barely turned on.3rd trimmer. Works well, gets hotttt, long time to cool down.But it does make a sharp line up, i would not use it on back of neck,that area always gets chewed up by this machine.
