Guys, from your varying comments, it seems that this is not unexpected. I'll shy away from them in the future. Those new GripIt plastic ones look interesting...
They're a fortune and the hole they leave behind, should you ever want to move what ever it is you've hung, will leave a right mess to fix.
If it were a choice for me between these or spending on a RawlPlug gun and expandable metal fixings, for the bit extra, I'd go the rawlplug route. Not to mention they're tried, tested and solid.
Dragons Den has a lot to answer for.
