Hi. Am using this product since 5 years.
It’s really good one, and cost effective. Their is adjustment for size so u can adjust the size as your wish, and till now I didn’t get any problem with this product, this is handy to use,
For one time charge this product can be used up to three times. Only thing is its not washable, not waterproof. But u can remove the blade easily to clear dust and hairs which are stored below the blade. By the brush which is given in the product box. U can buy this product without fear.
