Works great! No chemicals, no plastic, no 'heavy metals' , feels good on the skin.
Been using these for years. When I first started it took a few days to work well, like the body adjusted or detoxed. You can also trim your underarm hairs (once), as the b.o. lives in the hairs, this helps faster. Or use it more frequently to start off.
For me it worked straight away, after loosing my last one.
Give it a try
