:: Updated Review :: I bought it during Prime Day for just $40. I have a more expensive Black & Decker cordless drill and for small projects at work all I needed was a cheap cordless screwdriver. B&D takes care of my heavy projects. After receiving it, I noticed that there was no difference between high and low speed. I contacted the seller and they answered me perfectly and even took photos of some of the instructions. Turns out it's a clutch-based system, so the RPM you hear is the same whether it's set high or low, but the rotation of the bit changes depending on the setting. Basically it works as it should. I literally just disassembled a medium sized computer lab (disassembling furniture, screwing monitors to brackets, etc.) and had no problems. I only used one of the batteries which lasted the entire project which took about 2 hours. The battery was still strong so I'm sure it would have lasted longer. The batteries are small so I don't expect them to last much longer, but for light to medium projects this should do the job just fine. The general build quality is what I would expect from something at this price point. Not a commercial instrument, but great for home or work use. All in all, for the price I paid, it looks like a decent cordless screwdriver/drill with a diverse range of accessories. Add the support I received from the seller and I rate it 5 stars.
