I like the idea but honestly $185 USD for a stick with some LED‘s? No wonder they pretty much have no backers on their kickstarter campaign. As I said I like the idea and of course this has a good potential to really save lifes but with that price you can easily see the intentions of the producer (making money no matter what). If you are conserned about your elders just buy them a LED strip and tape it to their walking stick an show them how to put it on (about $10 USD on Amazon) and they can still use their favorite walking stick.
