MADE IN USA - When it comes to protecting yourself and your loved ones, how can you really know which pepper spray is the most effective? Although many brands claim to be the best, we recommend you consider the unbiased results of an independent laboratory* that tests the heat of the pepper once it is sprayed out of the can. This Certified Heat Rating (CHR) measures how hot the pepper spray will be once it hits your attacker. Streetwise 18 Pepper Spray has a CHR of over 180,000 SHU making it one of the hottest, most effective self-defense sprays on the market. For comparison, competing brands were tested by the independent laboratory. They found the average heat rating to be 123,000 SHU, making Streetwise 18 over 46% hotter than the competition! Streetwise 18 is so potent that it can incapacitate an attacker for up to 45 minutes without causing any permanent harm. Warning: some brands make exaggerated marketing claims. The only true way to know the actual effectiveness of a pepper spray is to have it tested by an independent laboratory. For us, "Protecting What Matters Most" is more than just a slogan. It is our commitment to provide you with a top quality self-defense spray that you can rely on to protect what matters most to you. *We have our pepper spray certified by the same independent laboratory (Chromtec LLC) that has been used by pepper spray manufacturers and the US government for over 40 years.
