here is all you gotta do if you sell products... just watch TV during the day and evening, pretty much any local programming or news and make note of how many lawyer commercials come on.
In any given day 100 maybe? Now... commercials are expensive so how do lawyers afford such things? They sue companies for all kinds of shit.
If you sell a product that could electrocute someone or cause them to electrocute themselves or installing it could accidentally cut their finger off.. or could damage their property.... or even if they think its scary and it causes them to lose sleep and causes "emotional distress"
People will sue for just about anything these days and there are no lack of lawyers to take the case.
