I use this lawn mower for my front and back garden, both are small.
these are the product details.

32cm Blade Length
Metal blade
It cuts the grass short and neat, It is very easy to get a even finish on your lawn, in little time.

1000W Motor Power
powerful enough To cut the grass quickly without going over the same patch again and again.
It is loud but not to the extreme it is quieter then some of the bigger mowers.

3 Cutting Heights(20mm-50mm)
It is adjustable but I have only used it on the setting it came on. I took it out of the box and just turned it on, so there is basically no set up required, apart from unfolding the handles (ill explain that with storing info).
This is short enough to leave about 1 month depending on the rate your grass grows and the weather.

28 litre Grassbox Capacity.
this is a large box If your lawn isn't to unruly you can go through the whole thing without emptying it (small lawn). The only downside is that the more grass it collects the heavier it gets so I would advise less able people to empty more frequently, or if the grass isn't that long to use without the grass box.

Weight: 10.5
You can pull and push this around one handed if you really like it's that light!
You can use it in the summer comfortably without getting to hot or tired.
I think that the weight of this would make it an advantage for more mature people who still want to take care of their gardens themselves.

To use the the mower there are 2 trigger like lever that is on the top handle bar, one on the left,one on the right, you push one down then press a button located on the front of the handle bar (so it won't turn on if you hold the trigger when transporting). you only need one pushed down at a time so it is suitable for left and right handed people.
Because the trigger is attached to the handle bar it is comfortable to hold down while still having good grip, a bit like gripping a bike handlebar.

The wire can get in the way sometimes. It wraps around the handle bars when stored instead of being a pull cord so you have all the wire out when in use.
The cord is 12m which is quite long, although I use a an extension because my plug socket is not near the back door.

Storing the mower is easy because it has screw handles on each side of the handle bar which allows the handle bar to double over, so it will be suitable if you only have a it small shed.

I would recommend this for people with small/medium gardens, but not for a large garden it's just to small.
