They are marketing this light as one you will never throw away.
It will probably be stolen before you get a chance to throw it away.
It will be interesting to read the reviews once this has been in the field for a fair amount of time. Don't the shake lights use capacitors instead of batteries? If so, I have high hopes for this new light since my shake lights hold a charge for a surprising length of time.
On the linked page, below the video, I found it ironic that they ask "Need extra batteries?".
