I am using this product for 1.5yr . It is still working very fine. It takes a lot of time to get charged. combs of 3mm, 6mm are available with this product. But it is very difficult to achieve a equal size beard as the combs are not so good. It is very durable. It has fallen numerous times from my hands but it is still working fine. Those who planning to purchase a beginner trimmer can always go for this.
