That looks dangerous as hell, the weight would have to be equally distributed on each side. Also don't even think about making any sudden turns to avoid a pothole, animal or small child.

Hmm, not much different than what we did as kids - put the bags on the end of the handle and attach a giant binder clip. My friend used a large rubber band to hold them on. The problem with having them on the handles though is you have to balance them out and you tend to kick the bags with your knees. I think I'd rather just strap a milk crate to the front.

Ridiculous! The problem isn't how to get the bags on the handle bar. Heavy bags (2 x 13kg) on the handle bar give you bike a will of it's own. After driving around a corner or avoiding an obstacle the bags will be swinging around and you'll have massive problems keeping direction.
I cannot see how these things will prevent any sideway swinging.

Carrying anything attached to the handlebars of a bike seems inherently dangerous to me. Even if attached securely, and roughly balanced at each side, shopping bags (e.g. plastic carriers as illustrated) will tend to swing with the motion of the cycle. This swing makes the weight of the contents, acting at the bottom of a bag act like a pendulum, making it more difficult to steer and also creating a varying force that can reduce stability, so increasing the risk of an accident.
So, while this might appeal to the occasional shopping cyclist, regular bike riders will know better and will equip their cycles to carry such loads safely.
Sorry but I see this invention as a dangerous option, to be avoided.

Dude, to start with get some canvass bags cause the wagging will break the bags and probably send your groceries flying. I suppose if you keep it low speed and you are athletic enough this might be an option but a rack or basket is a far better option. I don't buy that this orientation keeps the bag away from the wheel, gravity and inertia will not be changed by this. I see he has a bike without shifters and to create room for his hands he shoved the brakes so far inside that they are pointing forward because of the bend in the bars. Safer and easier? Just get a rack.

Why not just use your backpack? I always have my Dakine backpack on when I'm bicycling, and if I need a few things from the grocery store on the way home, I just park and lock my bike, and take my backpack into the store and buy what I need. It's comfortably balanced on my back for the rest of the ride home. These little "Bag Buddy" thingies, by comparison, make carrying groceries on your handlebars seem awfully unwieldy.

This seems cute, but it's a complete non-sense.
I've tried once to put my groceries on the handlebars and just did 5 meters from the superstore door out on the parking lot and canceled when tried to avoid few cars - as you begin maneuvering and everything starts to flip like crazy.
Doing it on a speed == suicide. Forget it. Just a "cute non-sense".
Best solution for groceries:
1) Cycling panniers 2) Handlebar basket 3) Rack basket 4) Trailer (but this is too expensive)
That's it. Proven.
However I like the guy's enthusiasm.

Accident waiting to happen. Manufacturer would get sued sooner or later.

This guy prefers to suffer all the consequences of continuing with a bad idea rather admit that he had a stupid idea. I got less than 100 feet before stopping and figuring out how to hang the bags over my shoulders.
Where does he shop that gives bags that you would trust to get you out of the parking lot?

Fine for noodles, but forget the milk
