SABRE Pepper Gel with Fast Flip Top, Maximum Strength OC Spray, Snap Clip for Easy Carry and Fast Access, Finger Grip for More Accurate and Faster Aim, UV Marking Dye, 0.54 fl oz, Easy to Use Safety

These are very nice quality and work well. They lock nicely so that I don’t have an accident. Easy to use and access. They are a great size and very powerful.

Nice little safety device for my wife and daughter to keep close at hand. Small and portable and best of all have not had to use one.

This is the one! I've found the Flip Top to be safer than the style with the locking lever. The flip top won't go off in my pocket like the lever did. The lever can gradually move into the discharge position, and then you have hot pockets. All Sabre products are excellent, and are recommended, but this is the one I use. It takes slightly longer to deploy by feel, because the top is uniform and it takes a little longer to locate the flipper. In situations that might require its use, I find the flipper and hold it in my jacket pocket.

I bought this on recommendation. Easy to hold with a key ring to hook on backpack or purse. Have t tried it yet, but carry it with me on walks. Glad to have it for extra safety.

So I don't know about their effectiveness because I haven't had to use them but they also haven't gone off by accident and are easy to handle. They are easy to carry and easy to conceal because of their size.
