I've no experience with those bolts of theirs. Interesting reading regarding the staple style ones. I've placed a number of the original short leg 'poxleys' - as far as I know none of them (mine at least) have failed...yet! The home made ones we made had a wider spacing and far longer legs. We tested these in shite quality sandstone using Hilti c100, their capsules and also their crappy c100-replacement stuff. We borrowed a hilti test rig from the shop (and broke it trying to rip the bolts out in the end)- we eventually managed to break the rock around the bolts - neither the bolts nor the bolt / glue never failed. placed a glue-in bolt in wet sandstone with poorly cleaned placement - this did eventually pull - but did so slowly rather than catastrophically. as for rotation of (non staple) glue in bolts - what we have done in the past is to recess the bolts so the eyelet is in a slot and cant rotate. of course this means chipping the rock using your drill - but a bolts a chipped placement anyway - only bad thing about it is it makes replacement in the future more difficult - and it can fook the bearings of your drill if you're not careful. as mentioned above - nae experience of the bolt-products glue-ins - i've just used eco-anchors (not so great), home made staples, various petzl glue-ins (great) and random stuff i've bought in france and spain (all back in '90s).
