I have used this drill several times. It works amazing. This saved me so much money. I used to have to be in a certain part of the house or outside within a limited range to get a Wi-Fi signal. And when it rained, it was a shitty shoot for WiFi outside or in the garage. I've used it to make my house completely wireless, including the garage and beyond. I'm not a professional installer, just a handy one. I definitely recommend it to everyone. Doing it yourself will save you a lot of Ka-Ching $$$$$$$$$$$$.
