The SeeSii WH700 is a 21V cordless 1/2-inch impact wrench built around a brushless motor, with two speed modes and a trigger that ramps up with pressure. It ships with two 4.0Ah batteries, a fast charger and a socket and screwdriver set, so it covers lug nuts and general bolt work without extra buys. Claimed peak torque of 479 ft-lbs puts it in the range of mid-tier cordless impact wrenches, below the flagship high-torque tools from established brands but well above compact 3/8-inch models. It suits DIYers and light professional users who want a complete kit rather than a bare tool.

The SeeSii 21V cordless impact wrench (model WH700) has a 1/2-inch drive and a brushless motor. It runs at up to 2500 RPM and has two speed modes. It delivers a maximum torque of 479 ft-lbs (650 Nm).
It comes with two 4.0Ah rechargeable batteries, a fast charger and an LED power indicator. The two speed settings (0-2600 IPM and 0-3300 IPM) are located at the base of the wrench. Speed also increases with more pressure on the trigger switch.
The wrench has forward and reverse modes with a locking mechanism. In reverse, a brake-stop function reduces speed and torque once a nut or bolt is loosened, so the fastener doesn't fly off. It is used for wheel nuts on cars, motorcycles and commercial vehicles, for bolts on doors, walls and scaffolding, and for general garage work. It can also drive screws for furniture assembly and other DIY tasks.
