I've been using these cheap screwdrivers for years. They won't be replacing my DeWalt cordless drill any time soon, or even close. Bolts that require very low torque and brittle applications that don't require you to remove the bolts. I like AAs because I don't have to worry about charging my batteries when I need them now. I see several reviewers rating it poorly. because they expect this little screwdriver to outperform their Milwaukee or Bosch drill bits. It is what it is, a $20 battery-powered screwdriver, and that's all I use it for, nothing more.
