I am using it since last years it is realy cheap in quality . It have some technical errors inside i, that should not be present in it. The good thing is that its battery backup is good. It takes much charging time around 4 hours to full charge. It is not much effective product but it is value for money.It should prefer others to use Phillips trimmers or other brands.But in this much money what you aspect. I am not much satisfied with this product.
