Thousands of people around the world testing and drinking clean water with Lishtot's TestDrop
We are happy when our customers are too
"I tested water in 3 new buildings and the water was good and when I tested water in an old building, I received Red. It seems like your device is accurate."
"since our new neighbors started to use our water source, we have suffered from unexplained pain. The TestDrop Pro has consistently shown that our incoming water is very bad."
"I tested tap water and it was red, then I tested my filter's water and it was blue. The TestDrop Pro gave me the evidence that I needed that my filter was working properly."
"I am originally from Germany but now I am traveling in Indonesia. I am in a very rural place and the TestDrop helps me to know which water can I drink."
"I compared the TestDrop Pro to a TDS meter, and I found the TestDrop Pro is more accurate and more sensitive than the TDS meter."
"I always wanted to know if the stream near my house was safe to drink, now with the TestDrop I know that sometimes the water is good and sometimes not. That makes a lot of sense."
The TestDrop has been tested by third party labs and companies
