Patanjali toothbrush is not that good as compared to its other products.
Tooth brush is definitely cheaper in price as compared to other tooth brush available in the market. It only cost you Rs 20 but it's not worth for your teeth. Bristles are soft but do not help you clean your teeth properly. Due to its design it will not reach or clean your upper wisdom tooth properly.
It's not lasting either. You will have to change the brush every 20 days or so because of the bristles as it will not be that effective in cleaning the teeth.
I would recommend this for travelling purpose as you don't have to use it for long and its cheaper in price.
