My goggles are still new to me. I have to spend more time trying them out but so far they hurt the side of my head. One of the features of the goggles is a rolling pressure on my temples which, in turn, causes my TMJ to be sore.
I thought it would be comfortable and relaxing, but it wasn't. The vibrations and massage was louder than I thought it would be. It didn't fit my face well either.
Very relaxing, and great for relieving headaches. I like that you can see the effect on your heart rate and that there are different modes for different goals.
A few ways I think this product could be enhanced would be with more content available on the Therabody app. It also doesn't entirely lay flat on my face.
