I'm sure those things are great for folks that have young children or grandparents with young children. But it's just the wife and I, my kids are grown adults and live on their own. We each keep loaded pistols in our nightstands, within arms reach. It would take more time for us to fumble for our eyeglasses than to reach for our pistols. Our two German Shepard's will give us the extra time needed to respond to a "bump" in the night. We have no need or desire to have one of those fancy gadgets.
