    Good tester kit
  

*by M***S on Reviewed in Canada on 2 March 2021*

Easy to use kit! Revealed we had no formaldehyde but did the job.

### ⭐⭐⭐⭐⭐ 







  
  
    Kudos to this Seller, low levels are difficult to discern but Seller goes above and beyond when I reach out to them!
  

*by F***L on Reviewed in the United States on 13 July 2018*

I have not submitted a review on Amazon before but I am so impressed I really need to do that now.I ordered two of these kits and they arrived on time, in good shape. There was a date of 03/19/2018 printed on the plastic overwrap on each package. I assumed, like many products, that this was an expiration date. Because formaldehyde is a very serious issue, and a known carcinogen, I was dismayed that I received what I thought was expired products. I submitted a question to the seller via Amazon and was satisfied and impressed with their immediate response.  Even though the package does have a statement about “Production date: see package” this is ambiguous particularly for something this important. The seller confirmed that the date stamped on the package is the production date, not the expiration date. So I am able to use the kits with confidence regarding the product viability.  In addition, the most critical color range is on the lower end particularly around the “safe” threshold of 0.10. The colors on the low end are very light and similar. So, I exchanged additional emails with the seller regarding possible improvements such as changes to the sample container and color card.  They were very open to feedback and as before, we exchanged a series of emails about possible improvements.I actually trim the excess white off the color card and lay the color strip across the top of the powder box to take the reading. This enables me to get the color card as close to the liquid without touching the liquid inside the powder box.  I’ve included an image of two samples side-by-side along with the color swatches.  I found it difficult to discern the score for the sample on the left and sent an email to the seller.  It’s not in the yellow/brown range (0.01), and it’s definitely not blue (0.15).  To me it looks like it’s in the green region but I could not distinguish between the 0.08 and the 0.10 score (safe threshold). I asked the seller if they would tell me what they thought and they quickly replied saying they consider this to be a 0.09.  This makes sense to me and I agree.This seller met and went above and beyond my expectations. It was very clear that the seller has thought through a variety of options regarding the ease of use of this product for a person at home, as well as the ability of someone to properly use and interpret the results. They are very open to improvements and are currently investigating improvements in the color card for future versions of the test kit.I originally gave this 3 stars due to the ambiguity when scoring the sample at low levels.  But, I have been repeatedly impressed with this seller’s attention to detail, their quick responsiveness, and thoughtful replies in our somewhat lengthy email exchanges.  While I do think photographic examples of control samples would help reduce ambiguity, the seller explained the difficulties and cost associated with this approach.  Based on my experience with the kit and the seller, and given the low cost, I do think this is a 5 star product and provider who has a genuine interest in the quality, safety, ease of use, and ongoing improvement of this product.

    Damaged product
  

*by R***A on Reviewed in Canada on 24 October 2023*

2 of the 3 kits were not useable as the solution had leaked out of the containers. Incredibly disappointing. Will be returning.
