yes. The stun is from getting hit by a thrown object. Object size doesn't factor into the range or the length of the stun either. So if you are using it, just grab a pebble so that the object you are holding doesn't obstruct your vision.
The stun animation length is the same as aero dash. It's around 2-3 seconds but unlike ebolt, your victim cannot shoot/use plasmid or move their mouse/stick. It's not a long stun by any means. It's probably the same duration as ebolt but it absolutely stops them from retaliating/escaping for 2-3 seconds.
If you are looking at it as a stun plasmid, it is not w/o disadvantages. For one it's a projectile so you have to lead your shots a lil bit. Two, once fired, it travels in an arc. That's something that you have to get used to. Third, it doesn't set your targets up for an easy headshot due to the stupid animation. Fourth, the range can be somewhat limited due to its nature as a projectile. And finally, you have to hold your 'use plasmid' key which consumes eve continously.
If you are going to use it as a stun skill primarily, it complements a close range playstyle very well. But even if you are not going to use it for stunning, it has an amazing utility. You can use red barrels, proxy mines and vending machine nades as weapons with the proxies and the barrels being OSK. You can use it to grab ammo or eve hypos from a distance. Most importantly, you can also use it as a somewhat effective counter against nade lawnchairs at mid-range. Heck you can even grab xbow bolts with it. So it's one of the better plasmids out there.
Btw, once you learn all of the red barrel locations for most maps, it would be in your loadout ALOT. People seem to think that heph is the only map out there full of red barrels. Aside from Medical pavilion (no red barrels) and Fort Frolic (only 2 red barrels), most maps have quite a bit of instakill barrels.
