Doesn't work. I logged in to bookbolt and then active extension, it populates and then before I can read it--everything goes away.

It does work, but if you're like me you use smile.amazon.com to make your purchases and have a small donation do to charity. Amazon smile doesn't work with this extension, you have to go to www.amazon.com. Once I did that it worked perfectly.

Is not working, it only provides partial information, without sales and prices, I can get better information just from amazon directly.

Doesn't work. I've tried everything including turning off pop up blocker and disabling my antiviral software. It just does not work!

So far so good. I was having trouble getting it to work also, but if you follow the tutorial on Book Bolt's page for installing and using KDP Spy you should be able to get it to work. I was using a link to Amazon from my bookmark bar instead of actually going to a new page and typing in amazon.com. Once I did this, everything worked as expected.

I am going with 3 stars simply because I cannot get it to work , so I don't hate it. I have installed the extension. It shows that it is turned on. I go to Amazon, type in a search for books, then go to my extensions. At this point I click on the KDP Spy and from this point on I have no clue what to do. Can someone please create a tutorial on how to get this extension to work properly? Just telling me to type in a search in Amazon first, then click on KDP Spy does not help me as nothing is happening. If I could potentially see what I am missing or doing wrong it would help my frustration level tremendously. Thank you.

I just downloaded this and it is working fine for me. Perhaps you're just not using it correctly. Make your search on Amazon first. Then click the extension button. I had to click on reset before it would load. Maybe that's why it wasn't working for some of you. Works fine for me
