I’m giving it 3 stars because sometimes my drill will stop working and say Error 2 and then later Error 4 and then starts working again, but other than that the drill works and I love the drill speeds.There are other information for this review, one is This reviewer did not purchase it and the other is 0 people think this review is helpful.
