The ray-board does help with shoulder and neck stress when using a kick board. I am 65 and try to swim laps about four times a week. Since using the ray- board, I have upped the number of laps I can do. With a traditional kick board, I often stopped because of neck and should pain, not because I was tired. I gave 4 stars instead of 5 because I think the board is way overpriced for what it is and I think the material it is made of will not hold up very long term.
