I ordered this product on Amazon, and as usual, delivery was super fast.
I hesitated between a rim size of this kind and ROTOFIL. Landscape I consulted advised me the ROTOFIL because the wire tends to pull the lawn. It is to this size shearing edge that I turned.
The product works perfectly well. The telescopic arm can cut the lawn without effort or bending in 4.
Without arms, I used to cut the weeds that grew.
No regrets for this purchase, I highly recommend it!
