After I put on the wax for 3 hours, my glasses started to fall off.
It's impossible to hold for a whole day. I bet some of those reviews are fake.
Or maybe it's not suitable for Asian countries due to the humid and hot weather.
After wiping clean and applying the product, the pair of glasses stays in place as advertised. Just that its resistance to sweat is a little bit weaker than expected.
I think it is worthing to buy the wax. And It becomes the details of my life.
