Three stars because it does its job, but you need to be careful before buying it so you don't get disappointed.
It's not for tall grass, it won't be able to handle it.
It's not for very dense grass, it will get stuck.
It's not for very small areas, you'll be going back and forth a lot (and it needs about a meter to start spinning with momentum)
You might need to go over the same spot more than once because (unlike those with horizontal blades) if this one doesn't catch some grass, it just "passes over it."
When I got it, my garden was relatively well-maintained and I struggled, but if the garden is "well-kept," "level," and relatively "spacious," it will work just fine.

Very good and ideal for a small space. Cuts with precision and quite quietly. However, it also needs the attachment for collecting the cut grass

I bought it for its supposed silent operation so as not to disturb the neighbors during quiet hours...
Failure! It is distinctly audible in adjacent residences and the surrounding area, so no one should acquire it if their criterion is not to disturb acoustically.
Also, the [optional] grass collection bin is essential because leaving the cut pieces on the mowed grass, I believe, acts toxically and suffocatingly on its healthy growth.

I return (after further testing) to urge you to avoid this design and functional failure as much as possible. If someone takes into account the purchase cost, the challenge from this specific company becomes audacity.
Stay away

Quiet, lightweight, very easy to adjust the cutting height. and effective. For a perfect haircut, I may need to go over the strip again. I wonder why I didn't buy it all these years.

The product offers exactly what it describes. Very user-friendly, easy to store without taking up much space.

Confidentially, the previous user's review convinced me to buy it. I can say that it helped me a lot. Indeed, very easy to assemble, one screw connects everything. Lightweight and easy to move (which plays a big role) and it shaves smoothly. The price held me back a little because it is a bit expensive, and when you order something online with a large amount, it is natural to have your doubts, but everything is fine. Personally, I don't mind that it doesn't include a bag.

Purchase for an area of about 75 sq.m. lawn. I have had it for a few months now and it has been used quite a bit, always on a level lawn.
Easy assembly, quality construction.
Adjustment for cutting height is very comfortable. Easy to use, does not require much physical strength (can be used by a petite woman or teenager).
Not dependent on gasoline or electricity, easy to store, quiet.
I consider it ideal for small gardens.
On the negative side, the relatively high price and the fact that one has to purchase an additional basket for the cut grass (which attaches to the machine, but needs to be emptied frequently...)
