Actually, they feel great on some B5 keymod handguards. I purchased two sets to mount on three handguards, and mount the scales at 10 and 2.
Certainly superior in grip and ergonomics to any VFG I've used and your fingers really 'lock' into them when gripped.
Considering what some people pay to have grips stippled, or what-have-you, I think the price is reasonable and I am VERY pleased with the product.
