Smartsonic Sonic Electric Rechargeable

i was excited when i receive this toothbrush but for my surprise when i tried to turn on i have to push like 15 time just to ear a loud sound with a burning smell the material quality is ok but is just not working i ask for a replace because i really want to tried i am so sad i received this for free in exchange for my honest and unbiased review
