I ordered this for a specific purpose but used a hammer drill instead and it worked effectively. However, I had to try it as I was so impressed with the video. I went to the back of the driveway/backyard below deck where my husband wouldn't see for a few years and tried this thing out. I am impressed. It really worked as shown in the video. Very easy, very fast. The filling material is not torn. I am planning to use it on a garage ceiling but would like to do some more research first. I would have felt more comfortable if the accompanying brochure was also in English. Or at least in Spanish - something I could type into Google Translate and read. This is not possible with Chinese characters. English is nowhere. The really beautiful case has Chinese characters cast on the front and the instructions are in Chinese ONLY. You really need a video so watch it carefully. I will also see if I can find more information about similar products online. You can understand that though, I did it and I was able to drive a bolt into the ground and that bolt isn't going anywhere.
