I have a medium sized garden but the lawns are in 4 smaller separate pieces and fiddly to mow because they also contain trees - so masses of edges to deal with. I didn't want to spend a lot and bought Flymo because have had their mowers previously and they performed well.
This one is no exception, it is lightweight and manoeuvrable and powerful enough for small-medium gardens. It has a roller for stripes which would work if I had a symmetric lawn without obstacles, but the cut is good and the motor powerful enough. It does the edges quite well - although watch out for decapitating the occasional flower ! A handy mower which I hope will give me decent service. Can't speak for its reliability yet, but previous Flymos have been good.
The grass box was a bit tricky to assemble initially, but once done it is easy to connect on and off the mower and it empties out into my composter easily enough. One small criticism which I think is true of many mowers on the market at this sort of price - it leaves some clods of grass on the lawn (even when the grass box isn't full), so there is some clearing up to be done after mowing.
On the whole, a good buy, performs well. I am pleased.
