No liners are perfect. "Kevlar" liners won't pinch your tubes. But won't stop thorns either.
Whereas these reinforced plastic style ones will stop just about anything. But may pinch your tubes.
I recommend these ones because they are exactly the same as other brands, but the cheapest around.
My advice is to wrap your liners in tape. Duct tape or electrical tape will do. Don't use flimsy tape like clear or brown packing tape.
They have their flaws. But I would always recommend these liners if you wrap them before putting them in your tyres. I have never had a pinch puncture since doing this.
