I have one of the bionic wrenches and want to let every one know what I’ve found so far. The tool works great, it holds even partly stripped nuts well. As you can tell from the picture it is not going to get into really tight areas. The nice thing for me is when I grab 3 or 4 wrenches and slide under a vehicle I can use the bionic wrench as a second insted of taking 2 of each wrench with me. All in all I like the bionic wrench it also works well for opening pecans. Which reminds me keep it out of the reach of children who knows what they will stick it there to crush.
