excellent grip and strength
Once pre-drilled into the concrete with a hammer drill, these fasteners bit in quickly and hold, even with an impact gun driving them in!

Great anchors
I held down some pallet racking and these are just as good as the similar Hilti anchor, for half the price

Just ok
While I'm sure these have a purpose, they are not really as good as a lead plug and lag bolt combo, the threads on the bolts are thin and pretty weak, they crush rather easily, and as a result, they dont have the holding force like other systems.

Not good
I bought 20 boxes and they worked fine.Than I bought 4 more boxes andthey didn't tighten and spun in the hole. I noticed they were made different probably a different manufacturer.

Didn’t hold correctly
It popped chunks out of the top of concrete and didn’t hold

Ease of use
They work like they are supposed to easy to use but they do work better in walls than flats the holes clean out better not causing it to dead head
