I saw it on sale in my local CVS and thought what a great idea! But like so many I quickly learned it does not work. And as I read what it’s does do it really doesn’t. It does not tell you what it is detecting in the water. Which was my whole purpose in buying. Companies like this are what is ruining the market. I would not recommend.

A for technology. D for customer focus. It should have been clear that you don't have to contact the water. "No need to touch the water!"Something like that on the outside of the box would have done wonders. I expected to dunk the thing into a glass of water. From the reviews I've read, I'm not the only one who felt that way. Let's face it; you name something TestDrop+; people are going to expect to drop it into the water.. it being a water tester and all. It works from my tests, but I can't see how reviews will trend to positive because the entire explanation of the process is confusing.

What a crock of dump. The only results you get are red orange or blue. Lead, e-coil, mercury, all of this and more it says on the box. More information in the app it says. Well the only info is red orange or blue. That is what you will get. And the same cup of water will test different every time. I want it to test my hopes and dreams but they always come back red.

Saw this at a CVS, thought it was cool, so I bought it. I went home and tested my tap water, which the device gave a score of ‘100’ with no amplifying information. I spit into the water, rescanned it, and got a new score of ‘18’. But still no amplifying information. Nothing telling me what was wrong, which the box for the device claims it does. I wasted $20.
