Great plasterboard fittings!
I'm just installing a new kitchen at present, and after taking out the old one, I needed to find new plasterboard wall fittings to mount the new wall and floor units. I've used the aluminium wall screws before, but I wanted to try something else this time around. I saw these Fischer wall fittings and they looked very well made, which when they arrived they proved to be. They go in to the wall very easily, and because of the thin metal shaft they pull themselves into the wall dead straight, which is brilliant when you're stood on a ladder and trying to balance and put these in at the same time. They also come with screws which are very strong. I'm now on my third pack, and I'll be back for more soon!

Excellent when used with care
Good product but you have to be very careful to insert them slowly. If you use a powered driver set on slow for use with dry wall. Too fast and the fixing just keys into the board and rips out leaving a ragged hole. Once you have the knack they are very good.

Solid work !
Easy to use for the bang average DIYer. Product works really well and much better than cheaper versions.

Good, but get it right first time
There are certainly easier and feel more likely to stay in for the long term than normal plugs you get in shelving/lighting kits which are quite honestly garbage..... HOWEVER, make sure you get it right first time as there is no room for error. They make a pretty big hole if you do get it wrong. I'd also recommend just using a normal screwdriver, not electric or worse an impact driver (for some reason everyone goes for an impact driver to screw in something that needs minimal torque then wonders why it breaks). Giving 4 stars not 5 due to the mess it makes should you make a mistake or need to take them out.

Easiest way to mount into plasterboard.
Simple to use just screw in. Decent level of support. They work as they are supposed to. The plugs go in a hell of a lot better than many other similar products. Very good quality product when your in a hurry.

Great for a single use.
I found with these that you can only really use them once and then if you try and undo fixtures the plasterboard fastening unscrews and completely wrecks the wall leaving you with a big hole. not a good fixture if you intent to trial fit something to remove for decorating for example.
