Sergio Bueno (ID: 0000008117260708) Voted 2 ★ - Updated 08/11/2022 This app doesn't give true numbers when it comes to limit buster. I even tested out my own offer on Amazon, and the amount of inventory for my listing is showing inaccurate numbers compared to my real amount of inventory. A competitors listing has has very inconsistent numbers when it comes to limit buster. One day it will show 999 or 450 etc.. the next day on the listing it will show 99 in inventory and then the numbers jump up. It doesn't do it job. I believe they are trying to deceive the public. I got contacted by a customer support person after I emailed them, and I addressed the issue, but never got a response again when I showed them the issue.

Regina Robinson (ID: 00000004e7fbd48f) Voted 1 ★ - Updated 02/12/2022 I used this for years and even had other subscribe to it. However I cancelled my account last year but it was renewed again 2 days ago. I cancelled again but now I want a refund. There is no way to send a message and when I try to submit a ticket, the CAPTCHA won't let me get past. This is very bad business. I wish someone would contact me and give me a refund.

Stephanie Phedula (ID: 000000cfdc0818ef) Voted 5 ★ - Updated 07/15/2019 Just got started selling on amazon and this is great. I'm not that great with technology and it doesn't get any simpler than this tool and even I can use it lol

George Willis (ID: 0000007e213b3ef7) Voted 5 ★ - Updated 07/15/2019 I was a bit skeptical after reading the reviews on here but the extension is working great and couldn't be happier. Support is on point and they have answered all my questions. I especially like the feature of seeing past seller limits.
