I'm impressed!

I was a bit skeptical that you could purchase a decently accurate water quality tester at this price but color me shocked.....it works! Tested this on a bottle of water and got 0-1 ppm (parts per million). Tested on my well water, which I'm aware has high sediment count, and got a reading of 115 ppm. According to the scale on it 0-1 is filtered bottle water and 115ppm is hard water. Went to my friends house who also lives on the same mountain and got 110-120ppm. So as far as I can tell it's fairly accurate. Very happy with this product!
Warning: This product may make you into a huge nerd... science... yay!

I live in California where the water quality is as healthy as fried chicken. This water tester helps me when I get my water at the water store and then I test the quality at each place. Or if I really want to scare myself, I test the water straight out of the tap... OUCH, toxic! I also may or may not have been known to take this on trips with me to test the water quality in other cities. It is strangely addicting and super easy to use.
Limited uses.

Seems to work for testing water solids in water which is what I think it was designed to do. I bought this to test the colloidal silver I make (PPM) so I would know exactly what I'm making and using. However, the colloidal silver machine manufacturer says the silver particles are too small (Micro-nano particles) to measure with this type of device. So I use it only to test the steam distilled water I'm using to make this silver solution and it works fine for that and for testing my tap water and bottled water that I'm drinking.
Can't complain too much about the unit as I get consistent readings from the same sample so its accurate but no way to compensat

You have to watch the temperature of the water as it affects the readings wildly. Gives me a decent ballpark number to test water filters as long as you can control the water temperature so it doesn't effect the results. Can't complain too much about the unit as I get consistent readings from the same sample so its accurate but no way to compensate for temperature so the number is kind of useless to me other than to test to make sure filters are working before and after installation.
Works well, great price!

Seems great, easy to use. Yes, there is a difference in readings between different water temperatures. But in my opinion are fairly negligible. Refrigerator cold, my reverse osmosis water tested 4ppm, but after warming to room temperature read 6ppm. And with our city water cold, it read 89ppm. After warming to room temperature it read 92ppm. As others have stated, it can read differently with varying water temperatures, but the difference is very small for casual residential use.
