fischer DuoTec 3/8" S PH LD

That's real Fischer Quality! It fits

It is by far the strongest plug that I know, I used to instal a heavy wall TV mounting for a 60 inch TV, I couldn't find a heavy duty plug reliable to install this mounting in drywall, since I found this one. Now is a indispensible part of my toolbox.

I returned them because I didn’t like the quality. I ended up using metal ones

The heads kept breaking off in the wall. There are better options out there

Bought some shelves from Ikea, and it looked like if the mount was not on a stud the shelve would come crashing down. Then I saw these things, and figured I'd give it a try. These are very simple to install, and looks great after installed too with the press-in-place grommet. The shelves were installed and felt as sturdy as if I had hit studs on all the screws. I'll get another box to have for just-in-case projects. Tip! Drill the hole with a 10mm drill bit (or equivalent in inches) and don't think, meh 9mm is just as good. It's not. :)

Easy to use. Make sure you've got sufficient cavity space.

初めて使いましたが強度もありそうでまた購入したいです

Fantástico para fijaciones firmes en paredes de cartón yeso.

Che dire, se la sono pensata davvero bene! Meccanismo ingegnoso che dà una stabilità senza pari, di semplicissima installazione e si aggrappa al cartongesso rendendola più ferma dei tasselli in muratura. Avendo diverse pareti in cartongesso, questa soluzione mi ha permesso di attaccare 55 pollici, mensole e quant'altro senza nessun timore. Eccellenti.

I needed 8 in total but luckily it's a box of 10 because I broke 2 in the process. So all good, but it has to be done very gently...

All fischer plugs are great. The do what they are meant to, easy to fit and superior quality giving you confidence that whatever you are putting up will stay there. These are for the heavier items such as shelves where you have a plasterboard wall and don't disappoint against expectations from this brand.
