They are good i have to admit, you don't have that worry that the pod will open when you open the strap to get it
However one did seem to open at the last NQ newbie day when it slipped out of my pack (i didnt put it in properly), it hit the ground and spilled 160 paintballs all over the nice green grass
EDIT I half agree with LemonadeX, if you are trying to put a locklid into a C5 pack while wearing the damn thing then FORGET IT, you just wont get it in
On the other hand it wont slip out
