## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Nice Rhinox drop checker
  

*by E***N on Reviewed in the United States on July 16, 2020*

This is a pretty drop checker that works as expected. The suction cup is staying put, which is good.

### ⭐⭐⭐ 







  
  
    It's nice but...
  

*by A***R on Reviewed in the United States on April 4, 2020*

Description says the kit comes with a 2ml syringe but I didn't get one. Also the reagent needs 4dkh solution which does not come with this kit which they should've noted in the description as well because the reagent added with tank water does not give accurate results.

### ⭐⭐⭐ 







  
  
    Decent product for the value
  

*by C***E on Reviewed in the United States on April 9, 2020*

Please don't day that you will give a syringe. That makes me feel unsure of this product. The quality of the glass seems good. It says to add 15 drops not 3. We will see how accurate this is.
