I am using this trimmer since 1 year, thats why I can say its actual performance that I had seen, the battery backup is not good and its always want to be pluged in for charge, low quality batteries, blades r not sharp enough to go through thick hair, in my suggestion I think its not work better for those who have thick hair, totally its not worthy of value we buy, there r other brands which can perform better than this, i think so, so I dont recommend this trimmer.
