  • (2020-12-08) Kevin E.: Shows the BSR but, not able to populate fields within the 4s product gauntlet using this plugin with the click of a button. Have to populate each field with the product gauntlet software. Not good.
  • (2020-09-06) Eugene Goyena: This extension replaces an older version. It´s not showing the BSR though, so in effect it cannott be used because the extension itselg won´t save the other data on the 4S gauntlet. Please fix the problem. No amount of refreshing, logging in and out seems to work. Thanks.
  • (2020-08-24) Mami Asakawa: I like it but I wish it had more features. Looks like it's in the making though. But all and all, I can't use it anymore because it stopped working. Now all BSRs are showing as 0. Logged in and out, refreshed browser, restarted computer, etc etc... anything I could think of but to no avail.
  • (2020-07-09) Ceren Yener: This extension only supports amazom.com and amazon.co.uk websites. It would be great if it would also supports other amazon websites such as .de
  • (2020-01-18) Neil O'Rourke: Really useful extenstion. Only issue for me is that the white text is difficult to read against the light blue background (bsr numbers). I would suggest darkening the blue a little to increase contrast.
