Product Review (submitted on June 27, 2012):
I use this during training and for powerlifting competition. It is extremely powerful, I can only use it with the cap slightly open as it is so strong. It is definitely the most potent smelling salts I have encountered, and is really good value, cheaper than other similar products elsewhere. It is important to keep the lid screwed very tight as the bottle seems to sweat a lot when not in use. Recommended if you want something to really open up your airways!.
