I have been using it for 2 months.
It does its job wherever needed, and with the twisting, it completely uproots the weeds no matter how big and deep they are. The only issue is when the soil is wet (muddy), the plunger requires a lot of force to throw away the debris. Also, when there are too many weeds, it is not suitable to use it, otherwise it will take a lot of time and it is probably better to use a lawnmower, digging with a hoe, or a hand weeder in this case.
Overall, it is recommended as a helpful tool that can be used occasionally, saving you from bending over too much.
