Effective but low-end lamp

In my case professional use, I put 2 stars instead of 1 because the lamp itself is fine job, I was very impressed by its light saw its price ... but the rest is really too low end The wall charger has burnt within seconds on the area so I could no longer charged with the cigarette lighter who also passed away after a week. Too bad because the lamp satisfy me in its benefits. Brief return to sender and fast refund
