Ease of storage was a must for me and the way it collapses makes it so easy to store, and the design makes it so quick to deploy and put away again, top marks!
The only slight downside is that beneath the deck there are so many nooks and crannies for the cut grass to collect in. This is the same for all the mowers I've ever used!

Like single line, swivel and extendable head, comfortable to use. Roller helps to position line , overall the best of several strimmer I have had.
Motor sounds a little ‘rattley’ unlike last one, swivel rotation stiff but hopefully will loosen off with use, last one was fine.
Hope this one has replaceable motor brushes unlike old model.
