This is one of my best purchases from Walmart. Nothing has failed yet in the year of me abusing them. I'm an Auto Mechanic and I use the driver for taking off nuts and bolts all the time. I calculated the torque, from the box to numbers I understand, and the driver puts out 112 foot pounds of torque. That is plenty for what I do.
One day I lent this out to my dad. He's a construction worker, and he was honestly amazed that these drills I bought from Walmart are holding up to names like, Milwaukee, and Dewalt. If you are on the edge, and don't know if you want to buy them, you should buy them. These are great products and will last.
