Great! and Watching for Improvements! Rated 4 out of 5 stars

I just started using this add-on, and I think it's great so far! I am excited to see some improvements being made to it, and wanted to share a few pros and cons . . .

PROS: In the description, it says that the plug in is non-obtrusive, etc. That is definitely the truth, as to be quite honest, I had forgotten that I had installed it, and didn't even notice the small dialogue boxes showing up.
When I did actually see the boxes showing up, I was actually impressed that it was working, and quite surprisingly did indeed find some better prices on the titles I was looking at . . . it really does save a lot of hassle in price comparing in different shops . . .

CONS: After paroosing around a bit on some different items and keeping an eye on the toolbar, only one time did the toolbar tell me there was a lower price, when in fact it was actually slightly higher that the item I was looking at. With the handyness of the tool however, I think I can put that aside.
It would also be great to see some settings for the tool. Perhaps an option to make it slightly more obtrusive, so that I don't forget to look down at the bottom of my screen when shopping. When I am shopping, I want to find a better deal, and if there is one, maybe I would like it shouted in my face that I'm spending too much money! Another idea which would be great, is to see more than one result, than just the lowest.
I do indeed like the unobtrusiveness, but being able to make it more or less unobtrusive at will would be a nice touch in the settings!

Thanks for the tool! I'm looking forward to an update! I think having more options, and 100% correct results would give this a 5-star rating from me!
