Rawl plugs.... wall plugs... whatever the f*ck they are called! They don't work.

Drill a 5mm hole through the plasterboard, chap the plastic plug in until it grips in to the plaster, hold your bog roll holder in place and screw the 2 screws in to the plug until tight.

Never f*ckin works, especially with the cheapo crap plugs you get with the bog roll holder, towel rail etc. They either push the plastic plug right through in to the cavity or simply don't tighten up.

P*sses me right off, as you can probably tell.
