We got these to add to our the flat part of our wall as slopers. They work well for this, perhaps being a bit on the easy side due to the raised logo. On our 25-degree overhang they work for stemming and bumping, we are not able to use them as a single handhold when overhung, too slopey for us.
The exception might be the teardrop shaped ones, these we can almost pinch enough to put all your weight on.
Glad we got these, they feel good and are versatile.
