Bests & Worsts Reviews from Amazon

This should be in every personal tool box. Especially if you every find yourself working between studs, joists or tight areas. Works very smoothly and dont think this bad bear only runs at low speeds. You will pass on it and realize soon enough you could have used it as it will surely be handy. If you are cheap f&$!, and expect to be able to use it in a commercial setting day in and day out over a course of time without replacing it, you are probably wrong. However, this should last a home owner a lifetime and should be considered as handy to a contractor. The bit it came with should last as long as you have a simple understanding of alignment to avoid stripping. The hex shaft is 1/4" and good for the drill/driver but also simply snaps in to the 1/4" cordless impact wrench. *For people such as the highest rated negative reviewer: This tool stripping out because of having to back out the screw or the screw freezing when driving in... The first thing to note is that this has to do with torque. Placement of a screw such as over a knot can also co tribute to the difficulty. Any bit will strip if you keep spinning it. If this starts to happen when using a drill/driver, think about switching it to an impact, if you have one. If you have one, it will increase torque dramatically and will likely get you right out of a rut. The simple fact is that from time to time, you may have to snip a screw off, back it out with grips or even abandon it, that is if you are relying solely on this, but an impact will likely turn things in your favor and also make the drilling super, super easy.
