The product looks cool and I am sure it operates well, but why and when do you need to shed your belt quickly? All I can think of is when you need to slash your son urgently before he runs away..
BlkicyIt's just convenience, saves you a few seconds a few times a day, and removes the necessity of re-adjusting your belt every time you wear it. Lots of people tell me they only adjust this belt every few weeks. I'm sure there are many specific reasons why it's useful to various people, child discipline and such (just kidding). Obviously not necessary for everyone though :)
