I feel no strength, just a little on the side.

Very disappointed. The manual is very basic, the vibration is annoying, and very little massaging actually takes place.

These are not great at all. They squeeze too tight on the temple. The buzzing noise is annoying. The pre-set music is soothing. The only really nice part was the heat on the eyes but I wish it was in different modes, there is only two and at the lowest you feel nothing. Overall, its not a good product. I don't recommend wasting money on this. I was disappointed given that the original price is a lot of this product.
