Strong!
These plasterboard fixings are incredibly sturdy and reliable for mounting a TV! 📺🔩 Installation was straightforward, and they held firmly without damaging the wall. I was impressed by how secure the TV feels—no wobbling or shifting at all. The fixings are strong enough to give peace of mind, even with a heavier screen, and they blend seamlessly into the setup. A solid, dependable solution for anyone needing to mount a TV on plasterboard—highly recommended! ⭐⭐⭐⭐⭐

Read the instructions and they work perfectly.
Worked perfect. Make sure to buy the starter kit here though as the box does not come with a 20mm bit. Drilled nice and slow and the outers popped in and the fish tails by hand. No hammers needed. No idea the issues some reviews are having. Easy as pie. Hung my TV no issues and super neat job. Measure three times. Drill once. My only quibble is the countersunk headed screws. I got them to work but they are very specific and the ability to have different threads and a flat back screw head would be good. Bar that. Zero issues.

Tap carefully
These work well but can be a pain to install. It's great that the pack in comes with the bit etc. but you have to be incredibly careful when you're tapping the anchor in to the cuff because it's pretty easy to accidentally tap a little too hard and push the cuff in to the wall or damage the area around it. Once their up, they hold a huge amount of weight and are very sturdy

Absolutely amazing fixings for plasterboard heavy duty mounting
I tried multiple plasterboard fixings from here, all seemed to have worked then failed after a few days of hanging a wall mounted folding ironing board. Then I came across these and was at first reluctant to drill a 20mm hole into the wall. But as I was left with 10mm holes already with the other failed fixings, I said let me take a risk. I am so glad I did it as this was easy to install and was so impressed with the design and the way the fixings actually holds to the back of the plasterboard. I now have a fully functional working Ironing board at my convenience! Highly recommender and great product that finally does what it says on the tin .. I mean packet 😂!

Amazing product, just what you’ll need for heavy items on plasterboard.
Very rarely write reviews but these things are excellent. Easily holds 6kg bookshelf speakers to wall mounts, 55” TVs and more and are all solid. The only thing I’d use again for heavy items. I did learn that once pushed in they may look a little off set but stick a small flat head screwdriver in and push up and down a little and levels up. Brilliant product. Just what I needed.

Used for 2 TV Brackets on Stud Walls
I've tried a few different plasterboard fixings, and these are easily the best I've used. I bought them to fit two TV brackets on stud walls and they felt much stronger and more secure than any others I've tried. Really solid fixings, easy to install, and they even come with the 20mm spade bit. Highly recommended.

Ok But
In theory these are a brilliant fixing , in practice I personally found them to be a bit a awkward to fit as the collar fits very easily but the 2 wing piece is overly tight and I found I had to cut small pieces out of wall to enable the wings to push in correctly. Once fitted I thought they left a bit to be desired and I wasn't convinced about them so I tried them with the radiator I purchased them for and they failed to hold it. I will say though if you have limited space on the rear of boarding these are probably a great choice for you it could be a no brainer as they require very little gap. I did also try the other type that you drill a large hole for push in and turn to operate the wings and I found those to be absolutely rubbish. So I ask myself was I expecting to much from these was it user error or was it my newbuilt walls were at fault I really don't know, there are lots of good reveiws for both of the 2 that did work for me so I must be honest it could of been my issue as much as there problem I have now gone back to the old metal star crush plasterboard fixers as I believe this distribute the weight over a bigger area and seem to hold better as well. I hope this helps with your choice.

Simply the best.
These are now my go to fixings for plasterboard and dot and dab walls. So simple and very strong, you even get a drill bit included. Excellent.

Efficacité
Très efficace, paraît impressionnant au début car il faut percer pour 20mm dans le placo mais une fois en place, cela tient fort (fixation paroi de douche). Même si le prix est plus cher que pour des Molly, je ne regrette pas l'achat, concept novateur.

Sturdy, but Tricky Installation
Works very well; however, installation can be difficult depending on drywall thickness. I believe the drywall was of standard thickness, but I still had to hammer the anchors in to be somewhat recessed to enable locking. It is strong, and I used them to upgrade a coat rack that kept failing previously. Now it has no issues with the weight of winter coats.

Extrem starke Dübel
Es gibt auf dem Markt nichts vergleichbares. Ich habe eine 80kg schwere Glasschiebetür damit an einer Gipskartonwand befestigt. Die Führungsschiene hält mit nur 6 Dübel bombenfest.
