I own and use a previously successful Kickstarter campaign product known as the Dacuda Pocket Scanner. The 2014 project resulted in a great working hand-sized device which produces reasonably good output.
My search for a link from which to purchase resulted in failure, as all indications (from Dacuda!) is that they don't and won't make them any more.
Strange enough, a generic search found this PenPower BeeScan device.
It is point for point and feature for feature the same scanner that I have from Dacuda. Off topic, I wonder if there was some intellectual property loss involved in Dacuda's decision to cease production!
My scans usually involve the newspaper and for that purpose it is excellent. As with all newsprint, the reverse shows through, which means I won't post a sample of that type of scan.
Lucky for me, I have one of a day-to-day calendar page which has opaque paper and no reverse bleed-through.
This was possibly a two-scan image, but the unit stitches pieces together very well. Occasionally it is necessary to make a second pass when things get out of kilter. The second pass usually puts them back in kilter.
It is bluetooth coupled to a tablet or phone and has very low latency.
I've snapped off a few photos to show the similarities:
