Not bad for first few, then baloney Rated 4 out of 5 stars

First it let me know where to save money, then it let me know I already had the best price on a few items, then lying to me and telling me where I could buy the product for a little more than one third of the price. Turns out its not even close to the same product model. Example: Search for Veho VCC-005-MUVI-HD10 Muvi HD 1080p on Amazon and it tells you you can buy this $139.95 product for $59 "buy it now" price on Ebay. Unfortunately the product they cite is the "Veho muvi Pro DV Camcorder" which you can buy on Amazon for $54.12 in the first place.
UPDATE: They apparently have fixed the anomaly and were very polite in their response, and all this on a Sunday. I'll give it another try. They shouldn't take the blame when Amazon puts up a wrong UPC.

This review is for a previous version of the add-on (3.5.2.1-signed). 

We've fixed the issue...

You are right, PriceBlink showed you a product that was not a match. It turns out that Amazon.com has the wrong UPC code for that product, which is why the toolbar displayed the wrong product (you'll note that it was a slightly different model in the same product line). Anyway, that shouldn't have happened, and we've corrected the issue.

PriceBlink is one of the most accurate price comparison services in the market, but in rare cases it mismatches products. I hope you'll continue to use the toolbar and am confident that you'll find it to be quite accurate over time.

In the meantime, if you find any more mismatches like the one you reported, please let us know by contacting our support team directly. You'll notice that inside the "Compare Prices" list, there is a "Send us feedback" link where you can let us know if we've made a mistake.
