  • (2022-06-08) JE L: works when I was able to use paid the 10 bucks and still says im on a free account and can only do 5 clicks a day. will be disputing with paypal if developer does not contact me back.
  • (2022-04-09) Kelly Livingston: What a scam! Stay from this company. The tool is worthless and always broken. Such a disappointment. Good like trying to get support from the developer. The extension keeps crashing.
  • (2021-10-27) Muhammad Imran: I just installed it but its not showing any results
  • (2021-07-29) Vlas Bashynskyi: It has a bitcoin miner
  • (2021-03-03) Jim Crae: I like the product overall, but not the customer service. This is the response they gave me when asking for clarification into why I could not see an accurate inventory total for Amazon on a listing. Please read their response below. Like we said, we can only show the data that Amazon allows us to see. This is not a magic wand into Amazon's databases. The product works retrieving inventory where items < 999 in 99% of cases. If you are not happy with that, then please cancel. There is nothing short of being an amazon data administrator that will give you the last 1% of inventory data we are not allowed to see. We may however be able to display when the inventory is masked in these cases.
  • (2021-01-25) jane philips: are you in need of a powerful professional and reliable hacker to help you gain access into others phone activities or hack into other privacy 🔏 and more, then contact [email protected] his service are one of the best of all time ⌚
  • (2021-01-03) Nyenda Robichaud: Does not work! I get a pop up saying: "We are sorry but the Inventory Spy Service is currently unavailable. Please try again later."
  • (2020-12-04) Angelina Aguilar: It's supposed to work for Amazon Mexico. I tried 2 or 3 items and it keeps "working" (yellow circle) but don't get any results, it kept working all night and still no results. Would really like to know if this extension still works and if it really works for Amazon Mexico.
  • (2020-07-22) Adam: As others have stated, only 5 clicks per day for the free app. Also, this does not tell you the accurate levels of inventory on Amazon - it ONLY tells you how many they allow you to purchase. For example, if a product has a 20 purchase limit on their product, this will show that there are (20) products left in stock, which is not accurate. All in all 0/5 if I could. Don't waste your time.
  • (2020-06-26) Venator: Alright.
  • (2019-09-03) John Kelly: Its a decent app but very slow. Also I thought it was free but after 5 searches I was told I'd hit my daily limit and I was forwarded to a buy page to buy the pro version for $9.95/mth. No mention anywhere about a search limit or a pro version.
  • (2019-07-31) Frederick Cabarce: i hope its free
  • (2019-03-27) Shai K.: worked at the beginning but then just stopped showing real numbers...:-(
  • (2019-03-24) Pat C: I was having a problem with the extension. I wrote the company and they immediately responded and asked what the problem was. when I told them, they came up with several things to try. Took about 5 minutes to go through their suggestions. Product is now back doing its thing. I love this product. I used it all through Q4. It's the only one I can find that really does all the inventory counts for an listing on Amazon.
  • (2019-02-26) William Otis (Leo - Wicked): Works well, not sure what the "1 Left (3 Total)" kind of responses mean - can this extension see past sales??
  • (2019-02-21) Aashpreet Kaur: Incomplete and incorrect
  • (2018-09-11) Robert Holl: Very disappointed Pay a lot for different software and this soon mounts up to a big bill, its nice when you see a FREE product, however after a few clicks u soon find out this is NOT FREE It is a decent program. I cant see why it is better than its competitors price or product, it does a small time saving job for a price.. Unfortunately if i purchased every little time saving product out there my monthly outgoing would soon shoot up. Review has only been left because false claims have been made about this been free, not the fine print of a few free clicks a day. I will be looking at other products that do the same job as my workload is high but i have lost faith in this program due to being deceived from the offset.
  • (2018-09-04) Alex Arvat: I have waited a couple of months to rate the extensions so I can have enough time to see how stable and good it was. After using it daily for more than 4-5 months, I can only give it 5 stars because it's simple but does what it says on the tin and in the 2 or 3 cases in which it showed wrong values, the support/development team were very prompt in answering/resolving those problems. Keep up the good work guys. Regards, a very happy customer (Alex).
  • (2018-08-12) Blue Kryptonite: It showed that I have 73 in inventory in stock when I never purchased more than 10. It has a bug and needs to be fixed.
  • (2018-06-10) Lori Balog: Wow!!! An amazing platform that actually shows results
  • (2018-06-08) Tried many alternative options before I came on this tool. Haven't switched to any other after this.
  • (2018-06-08) I wish I had found this amazing tool before. It has increased my conversion rate trifold!
  • (2018-06-02) Cueva Alexander: I absolutely love this tool! Recommended!
  • (2018-06-02) Michel Clark: Inventory Spy - a Life savior as I could price my products more appropriately and increase my profit margins so yayy!
  • (2018-06-02) ONPRE Mariana: Amazing FREE tool! Thanks! I suggested everyone I know to give it a try. :)
  • (2018-06-01) hency helen: Inventory Spy seems really suspicious at first but when one gets the hang of it, it’s certainly one-of-a kind tool.
  • (2018-05-29) Ryby Barbara: One of very few quality free Amazon tools that is actually beneficial.
  • (2018-05-03) Patty Trotter: I love Inventory Spy! It saves me a ton of time. Kudos to the inventors. ;)
  • (2018-01-14) Alex Arvat: Inventory Spy was just the app I needed. By the way, what does the setting ''Show Totals Next To Inventory'' actually means? Keep up the good work!
  • (2017-12-15) Bea Heitner: This isn't working. It only shows 1 quantity for inventory. I have latest version of Chrome how can I get help with this?
  • (2017-05-20) ken c: Developer fails to mention in the overview that in this free extension you only get 5 clicks per day. Any more than that requires purchasing a "subscription" costing $9.95 (One time? Per year? Per month?) Seems to be a deceptive start which doesn't inspire confidence in an extension which Chrome says can read and change data on potentially every page you visit.
  • (2017-02-11) Sager Davidson: SWEEEEEEET
  • (2017-02-10) Hieu Nguyen Trung: This is awesome!
  • (2017-02-09) deb taylor: This is awesome!! I have purchased this and use it every day! highly recommended!!
  • (2017-01-31) Jordan Taylor: I've found this to be the best inventory checker available. I use it hundreds of times per day and it's much more reliable and quicker than what I was using previously - How Many. I've switched my subscription over to this one.
  • (2017-01-30) DeAnn Jones: This is a great tool for any seller on Amazon. I found it super useful and use it everyday!

  • (2021-03-29, v:2.3.6) Ronald Samudio Valdes: Extension not taking me to offer page
    Inventory spy extension has not been working for me since i purchased it this past month.. when i click the extension to take me to the offer page it just slides out the offers (not the page) and then it loads forever and the orange ring does not disappear from the middle of the screen unless i refresh the page. This happens with every ASIN.
  • (2021-02-09, v:2.3.6) jc nicholson: not working properly

  • (2019-06-19, v:2.2.9) David Tamboli: Inventory Spy question.
    Let's say I run Inventory Spy and the results for a seller show (1 left : 4 total). Does this mean there are 5 overall before the seller sells out? Or only 1? Or 4? I can't find anywhere that shows exactly what this means. Thank you.
