ASP Metro Defender Pepper Spray, Self-Defense for Women and Men, Quick-Release Personal Defense Equipment, Personal Protection Device, Safety Running Gear, Personal Security Devices

This is the coolest undercover weapon I've ever owned. I do recommend getting the extra pack with the inert formula that way you have two doses of heat, the one that comes in the barrel and a replacement. DEFINITELY TEST RIGHT AWAY. I hope I never have to use this but I wanted to say something in response to the complaints that the Palm Defender isn't high power enough: If you are using mace that means you lost your chance to run away and avoid close range conflict. MACE IS A CLOSE RANGE DEFENSE WEAPON! Ignore the reviews about it not projecting far enough (the reviews that cite issues with the depressor probably just got the one bad one in the batch, doesn't happen that often and if you test before you rely on it, you would know if it needed replacing.) I absolutely love the natural grip, the rotating keyring turns it into a secondary weapon which if you have taken any self defense classes, you know the follow up action is just as important as the first strike. AND the safety isn't bulky and it WORKS! I feel safer, more badass, and totally nondescript with this on my keychain.

Supposedly there are three sprays in one of these little guys, so I tested one spray in the garbage can to make sure it functions mechanically and that the pepper spray itself does the job. Well it definitely works! Since it's a close range cone dispersal type spray rather than long range stream, there were particles released into the air, and I felt some of the heat. My eyes were protected by my glasses, but it did make me cough here and there for a few minutes. I'd say this is a last line of defense option. If you spray your attacker with this at close range, you will definitely take in some of it, too. Hopefully you only get some slight irritation while your attacker is severely crippled from the spray. I love that I can use the device as a blunt weapon, and that it's not nearly as bulky as typical key chain pepper sprays. I will keep a regular mini pepper spray in my purse along with this one on my keys. I'd much rather spray an attacker from 10 feet away, but if for some reason, I end up hands on with someone, this will take them down easily.

Very well made and high quality aluminum instead of plastic. Looks like a mini-flashlight so it is also very discrete. I have not used or tested it so I cannot comment on its effectiveness or range, but judging by videos on YouTube it should perform well. I like that it delivers a high velocity mist instead of a concentrated stream which should increase odds of hitting what you want. Amount of sprays is somewhat limited but that’s the trade off for a small package. I’ve had it on my keychain for about a year and it’s gotten beat up and thrown around but looks like it will last forever. It is designed with threaded end caps with o-rings that hold in the replaceable pepper cartridge so this isn’t a “one time use” device. Just replace the cartridge and you’re good to go. Overall I give it 5 stars based on quality, reusability, and discreetness. ASP makes professional level equipment for law enforcement and this little guy is no different.

I bought this to supplement my CCW. I was immediately attracted by its form factor and apparent sturdy aluminum construction. It's much smaller and slimmer than any other common OC spray I've seen besides a few in other kkeychain form factors. It is essentially an aluminum tube and so it can be used as a striking weapon though this particular version, the Palm is small in my hand. The end could be used if needed. I have tested it with the included heat canister and was happy with the result. I knew I was trading capacity and reach for the form factor and I consider it worth it. It sprayed in a nice cone/jet about 3-4 feet for 3; 1/2 to 1 second sprays. I sprayed it outside and felt some small effect just from proximity. Mild irritation and sneezing. My only concern with it is the plastic safety. I do like the positive safety mechanism. I prefer it's design to others I've had that could go off in a pocket or purse fairly easily. But it might become weak and break off. I'm not sure if ASP would cover that. It is also a little pricey. This includes the aluminum body itself, 1 canister of heat spray and 2 key rings. Each small refill is about the cost of most competitors products that offer much more volume and range , so that is a downside.

I exercise in a public park and I have been threatened by two off-leash dogs within a month. Since, I bought this, I have not had to use it for protection, but I feel much more secure by having it in my pocket. It's easy to use with one hand and it does have a finger activated safety switch to prevent accidental discharge. It's a solid piece of aluminum, so it could have additional use as an impact tool similar to a Kubotan for people who have some training in self-defense techniques.

I recently was put at increased risk and decided to begin carrying pepper spray at my family's urging. I chose this option because it is more discrete than a traditional pepper spray, and I liked that it doubles as a kubaton (which I have prior experience working with) giving you multiple defense options. Because it is not obviously pepper spray, I feel comfortable keeping it on me at work and I have a force multiplier should I ever need to defend myself. It is comfortable in my hand and fits well in the pocket of my uniform. While I don't feel "safer" per se it is comforting to know I have options if escaping or pepper spray misses or fails (there is a population of people unaffected by pepper spray and as well as who become enraged and fight harder rather than being distracted). I like that there is an option to purchase practice cartridges. Know your tools and practice with them. Running should always be your first choice if possible. Great option.

I keep it in my pocket at all times. Unlike a handgun, this is lightweight and comfortable to carry, which for me is a big deal. Also you can carry it into many places where guns are not allowed. Unlike a gun, with this if you miscalculate and use excessive force you will probably not be facing a long prison sentence. Seems to be more durable and better designed than the standard pepper spray. I chose the silver color because I thought the paint would scratch over time so I wanted the color to blend with the metal. It does sometimes tend to slip easily out of the pocket. People sometimes are not sure what it is so that provides some privacy. As a force equalizer I think it probably is a very powerful tool. Even a big muscular person it seems can be stopped to some degree with this, as well as I assume various animals. Against a firearm this might give some decent chance of defence. If sprayed in a closed room, even if not directly on an individual, it will soon make the room uncomfortable to stay in. Overall, this is one of the best and most convenient self defense tools I know.

I like carrying some form of OC, the problem I have with most OCs on the market is the form factors suck. My preferred product would be the Fox Labs 2oz cans, which come with a nice high quality flip top, but that can is fairly fat/bulky in the pocket especially if wearing jeans. But most smaller "pocket" size OCs on the market have cheap, chintzy tops with the style of safety that you turn to activate. I just don't trust these, both that the safety won't get turned in my pocket (which has happened years ago when I tried carrying one, though it didn't discharge) plus they are harder to find with your thumb and get the can oriented in the correct direction quickly and under stress. It's a shame they don't make the nice flip-tops in a taller, skinnier can. The only exception I am aware of as far as small cans w/ a good flip top, are made by Mace, such as Mace Brand Pepper Spray Police Strength 10% Pepper Pocket Spray . Sabre red also has a tall skinny .69oz product called a Mk-6, as does a brand on Amazon called Defense Technology, though unfortunately the mk-6 comes in a plastic sleeve that makes it almost as fat as the 2oz fox labs. Rant aside, the ASP defender series is a nice alternative in terms of form factor. The things I like about it are as follows - it's tall but skinny, so it doesn't provide a lot of bulk in the pocket. Because of it's length, it's easier to find in your pocket quickly, as opposed to other small OC cans that get "lost" at the bottom of your pocket. And due to the design, when it comes out (assuming you've familiarized yourself with it) you know exactly which end the spray comes from. It would be very natural to get this out quickly and use it, and know it's pointed appropriately in the guy's face. The safety is reasonably easy to disengage once you get used to it, as some others have noted I would recommend putting a piece of skateboard tape on it as out of the box it's a bit slick, and depending how it's rotated in your hand can be a bit tricky to disengage (they should texture the plastic). As far as form factor, the only real gripe I have aside from texturing the safety is it would be nice to have some kind of pocket clip option for those of use who don't want to use this as a keychain (I'll expand on that in a bit). That this can be used as an impact weapon is an added bonus. So, the negatives - the item description says this contains six 1/2 second bursts. I've tested it, using both an intert test cartridge and one of the real OC cartridges, and I think that's generous. From my test, I would say you get more like 1 good cloud out of this thing, after which the volume that comes out with each "burst" declines significantly such that you get like 4-5 more piddly little clouds. Make your first shot count if you carry this! And if you are facing more than one attacker you may be screwed. Also worth noting, the range is very short - you basically need to hold this right in the target's face. I don't really see that as a big negative as I see that the range I would most likely be using OC. But keep that in mind, and if you want more range look at something like the Fox Labs 2oz cans. I would be curious to know how the larger ASP Street Defender would compare as far as range and capacity, the description for that product claims thirty 1/2 second bursts. Related to capacity, the product description claims the canister for this product is 2oz. I'm not sure how they get to that, but it does not have comparable capacity to a Fox labs 2oz can (plus it's visibly a much smaller canister), and even the tiny Mace can linked above, I tested an old comparable sized can from Mace and got a good ten or more 1/2 second bursts (and those were real bursts, not piddly little fractional bursts like the ASP turned into after its first or second shot). That Mace product says 11g in the description which converts to .37 fluid oz. So again, I'm not sure where ASP gets 2oz from, but my tests showed significantly greater capacity from a .37oz Mace can, something clearly does not add up. As far as how I carry this, I don't use it as a keychain. There are several reasons for this, the first is just simply I don't want something that big/bulky on my keys as it's annoying. Also, if it was on my keychain I'm afraid I'd forget to take it off when I fly, and would forfeit it to TSA. Most importantly - if you are in a struggle w/ someone, it seems highly likely you may end up either dropping this after using it, or the key ring could break (esp if you used this as an impact weapon as it's designed) etc. causing you to lose your keys. Resulting in a) you no longer have a means of escape (car) or to get to safety (your house), and b) the mugger now is left with your house and car keys, sweet. No thanks, I'll keep my keys in my pocket where they belong. As I mentioned before, for those who don't use it as a key chain it would be nice to have some kind of pocket clip. Overall, this has the makings of something great but the capacity is disappointing I'm thinking of trying the larger Street Defender as I imagine that would give you a decent number of bursts. If you buy this, I would highly recommend test firing it with either an inert or live insert to see firsthand what the range is and the size of the cloud, then replace it with a fresh insert. Based on the limited capacity I got out of this, I can't imagine the smaller Palm defender having adequate capacity at all.
