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.

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

Fischer is my favourite wall fixings.
I always by Fischer rawplugs/wall plugs as they are one of the best wall fixings for all sort of loads. They are very strong and can hold any fixtures of significant weight. Please note that I am talking about all Fischer rawplugs not just this size. You buy fixings according to the nature of the job. These Duo plugs with screws are being used in my house to mount decorated shelfs not load bearing ones as well as medium size mirrors and frames etc. They do a great job. My only issue with this box was that the box was falling apart as it was soaked in some sort of oil and Amazon tape was wrapped around it to re pack. Few fixings were missing but it was still more than enough for me to complete my job so far didn't return it.

Reliable wall plugs with strong screws
I bought these to install 3 huge cabinets into brick. The wall plugs provide solid reliable grip into a variety of masonry substrates and have made my installation safe, bought for £6.01 directly from Amazon representing great value for money. I have since bought more without the screws for my tool box supply. The screw heads are though and are hard to strip.

Much better than 3M Command Strips
Very easy to use. I saw these featured in a YouTube DIY video, where they were rated as one of the best solutions for hanging pictures on internal walls. I live in a new-build apartment which has incredibly thin plasterboard internal walls. These have been perfect for keeping my large picture frames on the wall. (Far better than the stick-on srtips you can buy, which in my experience had a very high failure rate). Yes, it does involve drilling into the walls, but it's worth it to know I will never again wake in the night to the sound of velco strips failing, and picture frames crashing down.

Just get these, don't bother with anything else
I had a selection of screws and raw plugs, and was trying to put up some Ikea floating spice rack shelving. The walls weren't in the best condition, and no matter what I used, the plugs and the screw just fell out. I used these, and they were excellent. They fastened firmly, and securely, even on poor condition walls. Very surprised. Excellent quality. And reasonably priced. I will only buy these in future.
