I made holes in the wall for a TV mount, they seemed ok to me. The fact that the holes opened up is probably due to the wall and my lack of experience, it logically has nothing to do with the product.

They make the construction materials look like Styrofoam. Of course, always with a drill from the same company.

The most useless thing I have bought in a drill! Maybe I got a bad batch as others say the best about them.
Some of the five are crooked and with very little use they became very crooked (specifically the number 5 more, but also the number 4).
Not to mention that it doesn't drill easily. Chinese ones from Amtech have turned out slightly better for me, of course, also the B&D ones, not to mention the Bosch ones that are the top (but expensive). Even with Chinese ones, this hasn't happened to me.
I wouldn't buy them again as at this price, both Benmann and simply Bosch are in play.

For household use in plastering and wall construction, it is excellent.
Update:
In drilling for tiles, it managed just fine

Excellent quality, at an excellent price! It's not worth getting a no-name brand, especially if they are used for amateur use, as these specific ones will have a very long lifespan. They were tested on a stone wall, where they easily drilled 10mm holes.
