Overall score includes:

• Performance (50 percent)
• Ease of use (50 percent)

We test by cutting horizontally (levelling the top of a hedge) and vertically (trimming the sides of the hedge).

Trimming performance scores are based on how quickly and easily the blade cuts through the hedge and the sharpness of the final cut. Penalties apply for jagged edges and when we notice the trimmer struggling with thicker branches.

Ease of use looks at:

• The general comfort and ergonomics of the hedge trimmer, including weight, balance, visibility, and the ease of using the controls.
• The level of vibration.
