Review: Really good to use - Really like these. Good quality and accurate, in that the drill Size you need is written on the box. I have to admit it’s great having the plugs and correct screws together so I don’t have to scrabble about looking for something I’ve probably run out of.
Review: the best - These wall plugs are amazing and super secure. If you live in a tenement flat with concrete/brick walls these are a must and will hold up shelves and anything you need like towel rails and everything without you needing to worry about them collapsing or crumbling or coming loose because they really do be gripping hard. Honestly my go to wall plugs

## Features

- All-in-one solution for all building materials: The intelligent 2-component plug ensures top load values – the grey component automatically activates the optimal operating principle depending on the respective building material, while the expansion wings of the red component support safe spreading
