  • I don't think you can do any better for a homeowner. This impact is powerful, long lasting, and solid.

  • Great size, good tightening torque, but will only remove 40ft-lb tightned bolts.

  • Three little LED lights make it easy to see what you are doing, especially in dark corners or working inside cabinets.

  • It is a nice size as it it fits into smaller areas but has plenty of power. It has a nice feel to the grip also.

  • This is a very handy tool to have around the house. It is very small and lightweight but has enough power to get jobs done.

  • The largest bolt I can break loose with it is 1/4"(7/16 hex),or 5/16(1/2 hex),if it's not rusty.This is about what I expected from a impact this size.
