I am a keen squash player but being away from home I had to use loaned rackets from a pool store. The grips on them were shot at best (and they were relatively new!) so I bought some of this to get some grip back and it is amazing! I almost couldn't let go of the racket!
One 'application' lasted me two games (11-7, 12-10) and then the moisture on my hand started to take over, I still had more grip than without but was then used to the added grip with this. Now using my own rackets again it stays in the kit bag, just in case.
Comes in a sealed bag for longevity and a decent price, rapidly and securely delivered too.
