I would not consider this a self defense weapon. This will probably just irritate the attacker for a second.

Advertising this for self-defense is rather reckless, considering that people may rely on that.

It's pretty powerful and fires darn rapidly, those pellets are gonna hurt a lot. They penetrated a 2l plastic bottle, probably take your eye out ...

16J is pretty high, around air rifle levels of power so you could probably kill someone depending on how those discs damage people and how close you were.

Did you see what it did to a water melon? I think any intruder would be wise not to confront one of these.

I suppose you’re safe if your attackers are watermelons. But a watermelon is not a good substitute to understand what it’d do to a person. It only give an indication of damage.

What about a point-ed stick?

A banana?

If some homicidal maniac comes after me with a load of loganberries, I'll concede defeat.
