Since we live in an old house where some plaster more sand as usual contains what anchors are always problematic because often no firm grip. Since crumbles often times when tightening the anchor out. And you can not make ever greater dowel purely then, somehow looks ridiculous if a picture with 12er dowels to be fixed :-). But with this fix-it has almost always worked. In our dry, crumbly wall we have to water the hole well, and sometimes also use 2 FIX-IT, so that it raises well. One point deduction is available for the price. 60-70 cents for a small, plaster-covered cloth plate is a lot. But I have nothing comparable, günstigers found for the quick fix.
