Amazon reviews: proceed with caution

To all my readers: when buying a jar or can opener based on 5 -star reviews beware that some Amazon reviews do not match the product that is supposed to be reviewed.

The question I often get

I like to get questions from my readers. And I always answer all inquiries.

Because one particular question repeats quite often – I decided to write a blog post, so all jarandcanopeners website visitors can benefit.

Note. This post may contain affiliate links. Read full disclosure for more information.

The question goes like this:

Why don’t you recommend some of the jar and can openers that have almost all 5 star reviews on Amazon?

My answer:

It is because I care about my readers. I make thorough research and go through reviews very carefully.

I want you to become aware that some jar and can opener reviews on Amazon (especially battery operated ones) do not match the actual product that is supposed to be reviewed.

I am not alone in spotting this issue. This is what Business Insider wrote:

  • Some Amazon product listings have thousands of reviews describing a different product than the one that’s for sale.

  • According to BuzzFeed, some sellers are changing listings to advertise different products from the ones the listings were originally created for, taking advantage of the good reviews a particular item has built up.

  • This practice is prohibited by Amazon terms of service for sellers.

See for yourself

1. Take a look at the glorious (more than 386 customers) reviews that are placed on Instecho electric jar opener. It turns out that the majority of those reviews  are actually about  a lemon squeezer and a coffee press.

Some customers caught this “mistake”, see what they think of it here and here.

2.  Instecho Chef’s Best Choice electric can opener (wine color) is actually a hijacked thread of 514 reviews of a utensil set.

Just scroll down and see pictures of utensils posted by reviewers.

3. Here is another Chef’s Best choice electric can opener by MIToo (looks exactly as Instecho #2, but in black). While scrolling and reading reviews you will discover that 3180 customers gave high rating to a juicer, not to this can opener.


Update. June 28,  2019.

I am pleased to announce that  the issue of “hijacked” reviews came to the attention of Amazon and at this time (June 2019) the reviews of the items mentioned below are now: 

  • indeed matching the items sold, or
  • the page was removed from Amazon, or
  • product became discontinued, or
  • another high reviews item thread was “hijacked” 🙂 and now is featured in this article as items 1 – 3.

I decided to leave the article below the way it was written two month ago to raise the awareness that review “hijacking” is possible and can move from one thread to the other, and it is always a good idea to scroll down to confirm that the reviews are really matching the item reviewed before making a purchase.


4. Here is the other electric jar opener by Koyrau – more that 900 reviewers, almost all 5 star reviews. But when you look at reviews closely- they are about wire shelving units, not about the jar opener. Weird, isn’t it?

5. Moving on to can openers: according to the product picture and description you might think that more than 1200 reviewers were satisfied with Instecho battery operated electric can opener, but in reality they were reviewing a waffle maker.

6. One more example of Instecho “switcharoo” smile : you assume 800 customers were praising red Instecho battery operated can opener, yet reviews are about MalloMe tumblers.

7. And here we go again: another battery operated electric can opener made by Dopa (with Instecho brand on the picture though wink).  Again near 600 reviews, almost all of them 5 stars. But are they reviewing this can opener? You guessed it – nope. The reviews are about a candy thermometer.

And the list can go on…

I do not know about you – but something tells me to stay away from Instecho can and jar openers.wink Common sense, perhaps? smile

And, with my clear conscious I can’t recommend such products to my readers.

Additionally – no one product recommended on this website was ever returned. On the other hand, few openers that were not recommended, but bought by customers just because they saw a majority of 5 stars reviews without realizing that reviews do not match the product, were returned because of poor performance.

I do not blame customers that didn’t have time to go through all reviews before buying an opener, who has time for that these days? That is why niche websites like exist – make thorough research to simplify your buying decision.

In conclusion

I want you to be aware of existing  problem: in some instances reviews on Amazon do not match reviewed product.

And, please, remember, when you are buying a product from Amazon – look past 5 star rating, scroll down and actually read the product reviews.
