Get the job done without any pain
This is great. It always worked. This is much better than the one behind ears. Those which are for behind ears hurts much more than i thought. But this one is amazing. The only downside is the sticking glue/tape will become bad usually after 2/3 months of use. It happens with me several times that i lost one of the pad as it falls while i was walking. So i took multiple pieces now in order to replace it instantly.
