Is the Untimaty impact wrench worth it?

For light car and home jobs at a budget price, yes. If you regularly loosen rusted truck lug nuts or work all day, a higher-torque name-brand wrench is a safer buy.

Will 320 ft-lbs remove lug nuts?

It should handle most passenger-car lug nuts torqued to spec, especially with a charged battery. Heavily rusted or over-torqued nuts may need a breaker bar first.

How long does the battery last?

The 3.0 Ah battery gives short bursts of work, such as a set of wheels, but drains quickly under continuous heavy use. A full charge takes 2-3 hours.

What comes in the box?

The wrench, one 21V 3.0 Ah Li-ion battery, a charger and seven sockets. Check the listing for the exact socket sizes.

Does it use standard 1/2-inch sockets?

Yes. The 1/2-inch square drive takes standard impact-rated sockets, which are stronger than chrome hand sockets for this kind of torque.

Budget tools like this usually drop around holiday sales and back-to-school events. Compare the live price history before buying rather than assuming the list price is the low.
