Does a great job highly visible. Works well with the different fencers that I use in the different pastures. Last a long time. Can't beat it for the price.

Positive

I was very excited to buy this scanner and was pleased with its size and weight. However, if you have a Vista operating system, like I do, IT WILL NOT WORK! The company told me that they stopped selling this product over a year ago and there are no driver updates available for this product. If you have an older computer and an older operating system this product might work for you. But as for me it was a waste of money!

Ex Output:
Negative

Ex Input:
I wanted to read this book because the simple life of the Amish people intrigued me.I wish this lady would have talked more about the Amish.Instead,all you read about is "Me,me,me"."What am I doing in my life?"Why do I do this/that?" blah blah blah.By the end of the book the reader really doesn't care anymore!It was scarey for me to find out that this woman is a therapist-YIKES!The reason I gave it 2 stars is that (1) When she does talk about the Amish it is interesting (2) It is a short book and a quick read.

Negative
