Obviously the bracelet will not stop the gun owner from suiciding with the gun. However, it will stop the owner's kids from doing so.
Another thing about suicide: while many suicides are attempted, people who use guns in the attempt are far more likely to succeed than people using other methods. Taking pills, etc., allows time for regret and possibly calling a suicide hotline to be saved.
And you are damn right I have an agenda. I see the NRA and their ilk as stoking fear in the public in order to increase sales for the gun manufacturers (Glock, Beretta, etc.). Who do you think gives the NRA most of their money? It's not the members.
Here's a quote from NRA Executive Vice President Wayne LaPierre at the latest NRA convention:
We know, in the world that surrounds us, there are terrorists and home invaders and drug cartels and carjackers and knockout gamers and rapers [sic], haters, campus killers, airport killers, shopping mall killers, road-rage killers, and killers who scheme to destroy our country with massive storms of violence against our power grids, or vicious waves of chemicals or disease that could collapse the society that sustains us all. I ask you. Do you trust this government to protect you? We are on our own.
Can't you see that this is all an attempt to make people be afraid, very afraid? And to also not trust any external agency to protect you from all these threats. Why? Because that fear motivates people to buy guns, which enhances the profits of all those gun manufacturers that bankroll the NRA.
It a wonderful racket.
