When I first bought this drill model it worked perfectly. This is the 2nd one I've bought. I bought the second one a year ago. I have benefited a lot from it. I liked it so much I bought a second one to carry around in my RV. Then the trigger didn't work. I pulled the trigger and the light came on but nothing else happened. No rotation, just light. I contacted support and they sent a replacement straight away so that was good! Unfortunately, the plugin also failed right out of the box. Remember I noticed I bought an older one of the same model. That hasn't worked lately either. His trigger works, but only at full speed. It has lost the variable speed function. At least it works, but for how long I'm not sure. So from my perspective I had not 1 but 3 drill bits of the same model and none of them fired. I have no confidence in the product and this is a warning to potential buyers that a trigger will make you very unhappy.
