## Before you buy

- The listing gives an 800 N·m torque claim, but customer feedback is mixed: some report strong performance while others say it is weaker than advertised, including one report that it could not loosen lug nuts at 129 foot-pounds. Treat the figure as a listing claim, not a guaranteed result.
- Kit contents are contradictory: the explicit included-components field names only the impact wrench, while the title and feature text claim two 4.0Ah batteries, charger, sockets, bits and a case. Confirm the selected listing's package contents before buying.

## A good fit for

- Drivers or DIY users seeking a cordless 1/2-inch impact wrench with three speed settings and reverse operation.
- Buyers who want an LED work light and a reverse stop feature for loosening fasteners.

## Less suited to

- Buyers who need dependable, verified torque for especially tight wheel nuts or other demanding fasteners.
- Anyone relying on the advertised batteries, charger, sockets, bits or case being included without confirmation.

## Customer feedback

Customer feedback highlights perceived good quality, value and battery life, with some users appreciating the impact function for wheel nuts and tightening. Reports of power and torque are mixed, ranging from handling 4x4 wheel nuts to failing to loosen lug nuts at 129 foot-pounds. For buyers considering the listing's 800 Newton Meters claim, that variation makes demanding fastener work a use case to approach cautiously.
- Positive themes: Customers describe the wrench as good quality and good value.
- Positive themes: Some customers report battery life lasting a good while and appreciate the impact function.
- Negative themes: Some customers say the wrench is less powerful than advertised, with one reporting it could not loosen lug nuts at 129 foot-pounds.
- Mixed feedback: Reported torque performance varies, with feedback including both success on 4x4 wheel nuts and difficulty loosening lug nuts.
