When considering purchasing pepper spray for personal safety, it's crucial to evaluate several key factors. Firstly, ensure the spray has a high concentration of oleoresin capsicin, which is the active ingredient that deters attackers. Secondly, look for models with a reliable continuous spray over those with bursts, as this provides a more effective defense. Additionally, consider the pepper spray's safety features; a model with a key-lock feature can prevent accidental discharges. Check the spray's range and aim to choose one with at least 10 feet of coverage for optimal distance. The canister's size and your comfort with it are also important; select a pepper spray that fits well within your hand and is easy to carry. Lastly, review the legal restrictions in your area to ensure the pepper spray you buy is compliant with local laws. By focusing on these aspects, you can confidently choose the right pepper spray to enhance your safety.
