it's cheap and it works

Strengths:

cheap
no external power supply required, it runs off USB
small physical size
Take it with you on the road, and use it in the car.

Weaknesses:

I won't lie, it's a little slow.

Summary:

I've had it for three months, it works well. We use a similar scanner at work, that's why I decided to get this. I knew it wasn't going to be fast, but I don't use it often.
I would recommend this to a family on a budget, or anyone that needs a scanner one day out of the week.
