What the buyer should note while cleaning his plate: "Keep the cleaning tool pictured above with very much calm and patience perfectly horizontally, thereby sensing the pressure point exactly least".
I've only once a complete scratch cross drawn over the plate because I'm attached to the aluminum of the brush on the plate. And I'm not a gross motor type.
I therefore equal ne plate crashe I would not have thought and was rather frightened.
Conclusion: "you always get what you pay for"
This brush is really "very low" and it works for that matter dust removal. The bristles are just thinner and shorter. Useful for owners with wenigern plates have eg not very much drives value, certainly.
Otherwise, I can only advise against buying.
