I brought a lawn scarifier from VonHaus. On the first usage five of the ten blades broke
Ordered new blades from VonHaus and they sent the wrong spares
Von haus don’t have spare blades any more
As they have sold out due to high demand
That would suggest that blades are a major weakness with VonHaus lawn scarifiers
I would not recommend VonHaus and their customers support asked some very stupid question before giving a refund
