The best wall plugs I have ever used. However, its price on Skroutz is higher than what I found at a physical store outside the city!

Very good quality Oupa, but very expensive on Skroutz. Check also in a physical store. For this money, I got twice as many.

I installed them on drywall and the installation was very easy.
They hold very firmly.
I preferred them over butterfly anchors because they have metal on the inside, which makes them more durable over time, and in case you overtighten them (up to a point), the threads don't get damaged.
However, they are quite expensive (compared to the butterfly anchor), which is why I gave 4 stars.

I don't know why they even exist, for drywall they're useless, if you hang something on wood then they work. Generally, they don't even hold what they claim with the weight. A simple toggle bolt is 10 times better and faster in the job. Also, it seems like 4 out of 10 of these are always useless.

Very good quality, slightly high price. If you try them, you will reconsider what "oops" means. Also, where the simple ones fail, these anchor easily. Health
