I don’t know much of this brand before but since it is in such affordable price, I just gave it a try. It is a cordless set in a neat box. The clipper itself can be adjusted for 4 trim level (from 1mm to 1.9mm). Also the set came with additional 2 clips. There is a rechargeable 18500 battery inside the clipper. Since the battery is pre-charged, I did not get a chance to test the charger. However I used the clipper for about 20 min continuously and did not run into any glitch. It seems the battery can hold the power fairly good. I am happy with this product and will risk again with the same brand.
