I used it this weekend and I confirm that it is not super material. The main problem is the slider that adjusts the flow rate of spreading. It is too flexible plastic and when fertilizer is spread in the form of small balls, these balls are slipping between the strip and the frame. In this case, it is not possible to move this slider. We must first clear the device, chase balls with a screwdriver and then fill the device again (pity that amazon does not allow to put photos, it would be clearer ...). ELSEWHERE by the adjuster of this strip seems to me very fragile and I would not be surprised if it quickly makes the soul, and the strip itself, which would make it unusable.
In retrospect, I would have preferred to pay more and have better equipment.
Note: For products spread in powder form, it should be more suitable.
