Positive

With a 1.7Ah PowerStack battery it gives a perfect balance of weight, power and size, and is a must-have in their kit.

Positive

Stunning for its size, a bit noisy, drives big structural lags easily; planning to keep it until it dies.

Positive

Full power and speed jobs and tight quarters go to it, alongside a small quiet M12 hydraulic driver.

Positive

Laborer using it a few times a day finds the size perfect and has already beaten it up hard.

Positive

Modified with a 3/8 anvil for tight automotive work; a larger wrench has more power, but this stubby one wins on how little space it needs.

Positive

Converted with a 3/8 anvil, its shorter body removes bolts inside motorcycle forks where a longer wrench gets stuck.
