"Wow! I love golf and enjoy walking when I play. At 61 this isn't too much of a big deal yet, but ibuprofen was certainly on my 19th hole refreshment list. Enter the VERTX. Not a day goes by without others saying 'that's the coolest thing I've seen. Plus, my daily intake of ibuprofen has been eliminated, I feel a lot better and less tired after 18. Very happy with my purchase, thank you!!"
