Same for Speedy R - they are not 100% full. You can see in her second photo. My last one of the set broke in my hand. They're good for light work like breaking open a baseball cap, but if you want to put on a helmet, you get 100%. When it comes to adhesion, all with 3M Stick IF you clean surfaces TWICE. And all will detach or break on impact. It is best to attach a lanyard and clip to the helmet strap. And carry spares with alcohol swabs.
