1. Effectiveness
The effectiveness of the stimulus which is normally based on the "Scoville scale" in SHU = specified "Scoville Heat Units". The whole thing goes back to the efforts of pharmacologists called Scoville in 1912 - more information in the Encyclopedia of your choice, for younger readers: "Wikipedia".
Here is the SHU value of the raw material and the concentration of this substance in the solution, which is actually in the can is important. The latter is given as a percentage, so that the calculation is clear: SHU the basic material multiplied by the percentage of the solution = comparison value. This should be at or near 200,000 SHU. When FoxLabs "Mean Green", the values are lt. To the manufacturer on the tin at SHU 3 million for the raw material and 6% concentration, so mathematically arise 180,000 SHU of the final product.
2. formulation
Usually irritants - so even with this product - administered in two different ways: "spray" or "spray".
A spray does not require particularly accurate target acquisition, then, is a rather crude "space weapon". Therefore this variant is recommended often inexperienced users, which is subordinated to, "not aimed so accurately" to in a stress / panic situation.
Personally, I think of it - nothing. First, a spray is not concentrated enough - just a fog. Exact hits are possible, a gust of wind in the wrong direction can destroy the effectiveness of the defensive measure and possibly fogging the wrong people. This is worthy of prevention - both the "self-mutilation" of the attacked in a self-defense situation, as well as the inclusion of a bystander in the fog (the latter is also legally "problematic").
The concentrated spray jet is aimed directly against a possible attacker spared the defender (and uninvolved third parties), is more concentrated, so effective and allows a significantly greater distance from the attacker. In a self-defense situation, a more desirable circumstance.
3. amount of active ingredient
On the market displaying an extraordinary large number of irritant containers cutesy size, partly under 30 ml. While this fits nicely into small bags, but can "little something" to be in an emergency. Firstly, always something go wrong, on the other hand, the circumstances may require multiple sprays, due to robustness, resolution and number of possible attackers. 90ml I think is a good size ...
4. Special
Of the products market accompanying competitors, this product takes off by a factor which is indicated in the product name. The "nasty / vile green" contains next to the lovely main component an encore in the form of a really unattractive green dye. This can after successful defense of an actual, unlawful attack, in contacting the police facilitate the physical description clearly ...
I decided in the variant-90ml spray jet at the end of Mean Green of FoxLabs. Been used, it is not ...
I would also like the fact that in this type of product a date is attached (in the form of a month and year) in my copy 06/2017. This is to be understood as a kind of best-before date. After slippages of that date the product should be replaced. The "past" copy could then be used for training purposes, for example, but with care and caution:
In my experience, are also more expired products of this kind, "quite effective". So Access for testing inanimate objects such as tree stumps or targets to a wall and be sure to yourself nothing abzubekommen ...
