Listen, if your belayer's smokin a bowl while you are climbing, i'd rather have him using a gri gri than anything else...and personally, wouldn't want him belaying...
When i said completely, that was regarding the device...obviously if the person operating it is clueless, inattentive, whatever, you got serious problems...
We are arguing semantics here...my bad for improperly stating my opinion of grigri's
and necro...get bent...
