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! ⭐⭐⭐⭐⭐

Excellent fixings
Easy installation and the TV bracket is solid on the wall. Really impressed with how good they are.

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

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.

a hollow between the dray wall plasterboard and wall (if any) so that you can fit this fixture.
A cool idea, still struggling to figure out why such a large diameter for the fixing but, the wood drill bit is supplied. Don’t try and drill out already made holes. A useful but great idea that needs some work to improve its application. Perhaps a smaller hole size, perhaps a simpler centre fitting. Of course there’s many variations of this idea but. Nobody has really come up with the perfect answer. Definitely recommend, “if” you are willing to fill a bit when you don’t get the perfect hole. Hopefully this helps

Very strong and sturdy.
These work very well, especially where previous fixings have failed. Easy to push into pre drilled holes. Nice short screws to fix where void space is limited. Seems good quality well constructed hard plastic. Holding a heavy shelf well. Would recommend especially where previous fittings have failed.

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.

Great design for ANY plasterboard.
They work great in insulated plasterboard. Drill the 20mm hole, take a sharp thin knife,scrape away the insulation at top and bottom of the drilled hole. Tap in the round part of the fixing then place the arms of the fixing top and bottom so the arms open where you removed the insulation. Tap in with the hammer the arms will open up then screw in to complete the job. Very strong fixing. Says on the back of the pack they can be used on insulation backed plasterboard. Only drawback is you have to drill a 20mm hole to start the process. Don't be afraid to hammer the opening arms quite strongly, within reason. I used them to hang IKEA wall hung cabinets.

Used this for a heavy curtain rod that was installed improperly into drywall and had fallen out. The hole where the rod needed to be was ripped open and too big to use a regular anchor and screw. I had never seen this product before and felt a bit unsure about it at first, but it turned out to be easy to use. This product worked perfectly and provided a SOLID foundation. That curtain rod is going nowhere! Highly recommend.

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.

Novel idea, easy to install and super sturdy! Happy I found this product after previous wall anchors failed on our bathroom towel rack. Yes, the holes are larger but it allowed me to enlarge the previous anchor holes and keep the same mounting location. Thanks!

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.
