Lightweight & Cuts well.
The battery Life is terrible - lasted only 10 minutes on the 3 No. occasions I have used it so far whereby I was only cutting light grass. Very disappointing.

Orpington GB Many years experience.
Good all round streamer for small to medium gardens.
Already had two battery chargers fail and have had problems in replacing them.

Not powerful enough to trim a normal clump of grass growth. The string must be advanced often to be able to cut normally.
