Should have none there would be a problem when the owners manual says to ignore danger warning on drivers. Got it to work once and never again - finally threw it away.I will never by PenPower gear again.

This was easy to setup, calibrate and get working in short order. Bought for the wife to use for a research product, it took minimal training to get her using it smoothly. The software interface is top-notch and friendly - a great tool for the home.

Performs nicely but could use better software. At this early stage, you are limited to its use.

Doesn't work for Win7 64-bit systems, but I can still use it on my wife's 32-bit XP system. It's small enough to keep on the desk, does a great job of copying, no smeared or unreadable pdf files. Good deal & price.

Software incompatible with Logitech wireless mouse and keyboard. Freezes both.

Highly recommend. Low cost and clear scans. Files are automatically PDF format. Can save home and office documents in a more secure location than regular file cabinets. Takes minimal space in desk. Hundred of pages fit in any memory device. No need to...
