The batteries X2 last ages ..I've done at least 35 minutes and they still have charge for more .
It's quiet .
The 1mm strimmer wire is hopeless so you need 2mm , then the fun begins..the cartridge for the wire is overly faffy and frustrating ,this lets down the overall strimmer , I feel it will break as well ,very flimsy...I'm dreading changing the wire again.
the handle is not great either , that could break at any time . I think for my garden, it's probably not going to last , so we will see
