Because the price wasn't high, I decided to buy it and take the risk. I tried it where there was plenty of chamomile, but in the end, it not only collected it but also ruined it, besides being time-consuming. Maybe it would work well in fields with chamomile, but in pieces, it was useless! In my personal opinion, it's a waste of money. As for the construction, it is sturdy. With a modification in the teeth, making them adjustable so that the gaps are reduced, it might have been more functional.
