Once you login in the app, their is no going back even after you wish to stop them to not monitor your MWS Authorization. They will continue to monitor even after you uninstall the account, till you delete tour MWS or Seller account.

Someone said the profit analysis is the best function of this seller app.But I think the PPC automation is the best, does anyone agree with me?

I would like to give this seller app a big 5 star personally! I tried more than 8 related Amz seller tools and this the only one I keep deploy to my business, even compare to Amz official seller assistant app, the sales analysis and campaigns optimisation are really cool and efficient! By the way I think this is the cheapest and most reliable seller app in nowadays market.

Have you guys tried any of those 3rd party facebook campaign tools before? If so, there is no doubt that facebook did a great job to combine ads manager & power editor together; By contrast, Amazon sellers can only rely on 3rd party search campaign optimisor like Tool4seller.

hmmm,Now! I can save almost 2hrs of excel works per day since using this seller app. The dev. team did really a great job in terms of keywords ranking and profits analysis. No more rough guessing of my profit&loss for the day, the week and the month. I also like the feature of seeing the list of my top sellers with their pics, SKU and ASIN.

Excellent app. Used several like this and they didn't give me accurate data. A week in and ive checked the data v Amazon and its excellent. Also the widgets and functionality is brilliant. 5 stars. Only concern is Ive contacted support twice and no response which is a shame. Good product needs good support to make it a great product.
