It works great so 5 * review. As per the reivew from Maria, the 5/16" inch masonry bit in concrete will technically fit those plastic anchors but they are too tight and get lodged halfway through. Hammering them in after that risks bending them at the top which I did. Simple fix was use 3/8" masonry bit and they fit in good without breaking them (but not too loose either). If you are drilling into concrete you can use a standard cordless drill with a masonry bit but you have to use extreme pressure. Easier would be hammer drill with same bit but I didn't have that and isn't necessary. Overall, works great without having to mount to post or home.
