56833 First Defense 360 Stream MK-3, 1.3%

I used this exact spray on a man who was incredibly intoxicated and was trying to stab his wife with a very large kitchen knife with at least a 9” blade. It stopped him dead in his tracks, he tried to run away and didn’t get very far until he stopped, dropped to knees and began rubbing his face in the wet grass attempting to wipe the spray off of his face. Needless to say, his efforts failed miserably. Anaheim police came out, arrested him for domestic violence and credited me for saving the woman’s life. The man was transported to the hospital due to the level of pain he was in while cuffed to the gurney. I did capture the entire incident on video, gave a copy to the police and an officer made it a point to find me the next day just to say “GOOD JOB” after he reviewed the video himself. The officer then said that I not only convinced him to start carrying spray again (he stopped because of poor results) but he started carrying this exact same brand the very next day. I carry this everywhere I’m legally allowed to and I carry the maximum OZ size and strength allowed by California state law. It’s VERY effective and I trust this spray with my life! Unfortunately, I have used it for legitimate defensive purposes several times and it has never failed me! I would post the video on here, but it’s from my company’s facebook page which I’m sure Amazon would not allow as they would probably see that as a form of advertisement. I highly recommend this product and swear by it. But, keep in mind, if you use this product or any other pepper spray/mace products without solid justification, it is a felony and can land you in serious legal trouble as well as severe civil liabilities. Be smart when carrying and using these type of products. It’s for self DEFENSE ONLY! Also, I would strongly check with your state and see what the laws are in carrying and using pepper spray. I believe in some states it’s illegal to even possess pepper spray or Mace. When using any pepper spray or mace products in self defense situations, you ALWAYS firstly stay calm! But, you want to spray the attacker’s face in a “Z” pattern if possible. Meaning, first pass of the “Z” pattern going across the face hitting the attacker directly in both eyes, then, then second pass of the “Z” spraying the attacker in the nose hitting both nostrils, and the last pass of the “Z” pattern, spraying the attacker in the mouth! If you do that, the attacker will regret every life decision ever made, will fall to the ground in pain and will not get back up and will remain there until police arrive. Secondly, if you do spray someone. CALL 9-1-1 and STAY there if safe to do so. If you leave and do not call the police, you’re looking at possible criminal charges. If you de leave for safely reasons, at least stay close enough to where it is safe and call the police. When they arrive just tell them why it wasn’t safe for you to still be there. And then explain in detail what happens and what led up to the use of the spray. If you were justified in its use, you will have nothing to worry about and most likely never see a courtroom. Also take note of any security cameras you noticed that may have caught the entire incident. Again, as previously mentioned. Be smart about it’s use and never use it just because your were angry or your emotions were running high. That’s never a good reason and will land you in jail very fast! It’s ONLY FOR SELF DEFENSE pure and simple! Also, needless to say, (common sense) keep this way from children! Matter of fact, kinda treat it like a loaded firearm!

1) Yes, the Def-Tech 1.3% is about the most powerful pepper spray you can buy. The only other one that is close is the Fox Labs 5.3. 2) The "360" designation of this model means that the liquid is contained in a separate internal "bag", which is surrounded by the compressed gas. This allows you to get reliable spraying at sideways and upside down angles, which is very nice to have in a "weapon", as who knows what angle you might be able to get this into in a conflict. 3) These larger, round canisters (MK2, MK3, MK4), along with their larger flip tops, are the quickest to fire, most reliable and durable personal chemical weapon dispensers available. Yes, they are a bit tougher to carry in a pocket or bag compared to the smaller MK6 or various twist top canisters, but they are well worth carrying if you can manage the size (its a weapon, and speed, reliability and range are critical to ALL weapons... don't sacrifice any of those factors, if you don't absolutely have to!) 4) Some states (like California) still limit the amount/volume of liquid in a canister that a private citizen can own. In CA, the max is 2oz... which makes the MK3 canister the max size (at 3oz, the MK4 is over that limit, which could get you in trouble with law enforcement). There is no limit to canister volume in CA for registered security officers with an OC permit, or local or federal law enforcement. 5) Some pepper spray here on Amazon is listed as "Prime" shipping, while others are not. Keep in mind that by Federal Law, ALL pepper spray has to ship via ground shipping, so.. it's going to take 5 days to get to you, no matter how it is shipped. If the pepper spray is not listed as Prime, but is still free shipping (like this 360 version here currently is listed), then it really doesnt matter that it is not prime shipping. I received three of this canisters in 4 days after order.

Excellent product.

Used to carry this brand on duty as did all the deputies. Many deployed theirs and they always sprayed nicely. I am retired now and carry it now walking. I replace it at 5 years and empty the old ones. The old canisters spray fine after 5 years.

Ok, I’ve been using First Defense doe over 25 years now. I’ve seen their formulas improve over the decades and it’s nice to see the 360 design. When it comes to pure potency and pain delivery for compliance, this takes a back seat to Fox Labs. As someone who generally consumes a can a month, I rotate between Red Sabre, First Def DA 360 and FL SHU 5.3 based on what’s in stock. First defense is always my backup to fox labs but this stuff is still spectacular. I prefer the MK4 size but also carry a MK3 on my vehicles. Most effective 3-4 foot away due to the small 1.4oz.

So, I bought this stuff to throw in my car. When it arrived it was in a box with a nice cylinder plastic packaging. I opened it, read the instructions. It said to test product before use and that it is not 100% effective. Well I found out the hard way that is a damn lie. I sprayed a tiny amount in my kitchen sink and boy this stuff works. We couldnt go in the kitchen for a few hours even after rinsing it down the drain. We actually had to leave the house. My roommates and I were coughing our asses off for a good 15 minutes. Watering and burning eyes, throat, nose and face. My roommates both forced me to write this review asap warning of how good of a product this is. So I made sure to leave a good review. Have no doubt this stuff will work if needed in an emergency situation. Still reccomend carrying a firearm as well, but I also highly reccomend this stuff! 10 stars from me! Lol

I hope I never use this. I purchased it due to the positive reviews and the fact that this is a 360 degree canister meaning that you will be able to spray it at any angle unlike other spray canisters. This is a good feature because one is not always attacked standing upright. I have a perfect fitting holster for it, but it can easily slip into your pocket or purse. has a safety latch on top so you can't accidentally set it off. It says to test it periodically but I won't and just hope that it works when I really need it.

Quality product at a fair price that was delivered quickly and manufactured this year 2024. This is on par with Sabre Crossfire and affords deployment from any angle. Fits the MKIII holster perfectly. Very pleased and would purchase again!
