I give this product 1 star for its nice compact size and the fact that it is USB powered so no power cord is required. Also, despite the description, this scanner is not compatible with Windows 10. Don't buy and don't waste your time like me. I hope Revain keeps this review online. I heard they remove or bury negative product reviews. Hope this is helpful

WARNING! Bought this item from this retailer. When trying to register it with Canon, it turned out that it had a Canadian serial number and could not be registered in the US. I ended up having to speak to someone through the back door of Canon to find out why I couldn't register it. Canon support requires it to be registered before you can speak to a live person. Beware.
