Perfect for the right scenario
Great product for the ideal situation. 1 - other drywall studs have failed you leaving with a hole too big for other drywall studs. 2 - I have brick right behind my drywall so I had very little room for the traditional drywall stud 3 - you need something to hold a large amount of weight Only tricky part is getting it to line up. Not sure why it was so tough for me but I had to hammer it in. Didn't feel good but it worked.

Must have
I wouldn't hang anything from a TV (80") to anchoring stand alone cabinets with anything else very strong very easy to use

Worked as described
Great product, solved my issue with hanging a toilet paper holder on a wall with a pocket door.

They work, but be attentive when installing them
These aren't bad, but they lack perfection. If you tap them incorrectly they can slip through the circular support. The face of the anchor should be a bit longer so that when you tap them into position the face of it is held in place by the circular support. They still work, but you just have to be careful not to tap them too far. Also, if your anchors are too close together you can't put one on top of each other, unless you turn one 45 or 90 degrees. They still work if you do this, but the instructions will tell you to install them vertically. I wish the screws had a larger head and that the shaft was a bit longer. The screws provided might need a washer to prevent them from slipping through your bracket/frame of what ever you are trying to hang. Once installed they work good.

Great for towel racks that keep getting pulled down.
I have really old drywall in the bathroom and the kids and wife kept ripping the towel rack off the wall. I didn't want to make new holes to find a stud. I also tried this plaster drywall reinforcement product, but the drywall still crumbled. So tried these out as it creates a new larger hole over the existing and claims to support a lot of weight. This has now become my new drywall anchor for any place I need to hold significant weight! Used it for towel racks, and large screen tv mounts. Install is easy and device sits pretty flush to the wall. Recommend these to everyone for permanent drywall installs. The only negative is that if you need to change things up, removing these are almost impossible, and you will have to patch a large hole.

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.

Good concept, only works in perfect situations
This product advertises itself as a "universal" fixing "for all types of plasterboard". I bought it to hang a hidden bracket shelf in my kid's room after the regular anchor pulled out of the wall. I drilled the hole, shoved in the piece to expand that you're supposed to need a hammer for, and it expanded just by pushing, and then it wiggled all around in the outer ring. It definitely couldn't clamp on to my drywall. It seems like there is only 1 exact thickness of wall that this will work with and mine apparently is not it. It also doesn't make clear that it only works with the included "very short" screws, not regular drywall anchor size screws. They're maybe 3/4 inch long, so they won't work in a lot of different applications. It was easy to use, seems to be decent quality, but is very expensive so it's a poor value for the money. The functionality in perfect circumstances would probably be great, but for me, it definitely was not functional at all. You can see in the picture how for a thicker wall it'll sink in (making the short screw even more useless) and for a regular wall still not sit flush.

Best drywall anchor I’ve ever used
Installed 2 of these drywall anchors this afternoon. It was much easier than I thought it would be. I’ve worked with all types of drywall anchors and this one is the best one. My go-to for years was the EZ anchor brand with metal that hold 40 lbs. but after 20 years my coat rack finally pulled out of the wall. My teen son’s backpack is super heavy so I need something heavy duty that could hold 100+ lbs. but that’s not all that goes on the coat rack. Since May I’ve been looking until I came across BullFix anchors that hold 255 lbs. Anyway, they’re easy to install. I pulled and tugged on it to be sure and it didn’t budge. I put my son’s backpack on it and it’s still hanging on as it should!!

Positiv überrascht
Ich muss sagen, das ich echt skeptisch war. Ein Kunststoffklappdübel soll in einer Trockenbauwand soviel Gewicht tragen können? Aber erst einmal zum Verwendungszweck: In unserem frisch renovierten Badezimmer musste eine neue Heizung rein. Nachdem wir uns für eine Infrarotheizung mit Marmorplatte entschieden haben stand ich vor dem Problem, das das Teil 25 KG wiegt. Die Wand an die sie aufgehängt werden sollte bestand aus Gipskartonplatten. Hier auf Amazon dann diese "Dübel" gefunden und bestellt. Was soll ich sagen die Montage war recht einfach und die Heizung hängt. ICH BIN BEGEISTERT!!
