Maybe. It can technically be used for the whole game, with only a .5 second split in use if you wanted to keep it going. Despite this, it does have a rather short duration and if you swap  to your primary as soon as activated, attack, then switch back, you're a sitting duck for 5 seconds.

I've only ever really seen it when they're trying to make an escape, by which time they're usually low on health anyway. Its concept is rather similar to a Huggable secondary suggestion I shared with the BB forums a while back :P
