Appears accurate and really handy to have!
So this little baby let us know that the new home we bought has a refrigerator with the water dispenser/ice cube maker hooked up to a water source that comes from the softener! Seriously. What contractor does that? The prior occupant was an older lady who probably has sky high blood pressure drinking softened/salted cold water and ice cubes from the frig. That is so sad. The frig filter cannot filter out all the salt. It tested around 750 ppm. 200 less than outdoor faucet water. If it had non siftened water and a new frig water filter it should have tested under 100. Unfiltered tap water from the kitchen sink that isn't hooked up to a softened water source tested at 750 ppm. Water from the sink side reverse osmosis tested at 50 ppm. Distilled water (just for fun to see if the unit is anywhere close to accurate) was zero. Yay! The case is handy and it will ensure the cap for the unit won't get lost. The digital readout could be a bit clearer to read, but no real complaint enough to take away a star. The unit clearly warns that it is not water proof and to only submerge it up to 2 inches. We use the cap to hold the water for testing and then that ensures the unit won't get damaged.

Like iSpring's quality and pricing.
I bought this Hardness Test Meter when I purchased my iSpring RCC7 system. It works great and is a must have for an RO system. This unit is still working fine for the last 8 years, I'll probably have to replace the battery one of these days. I really appreciate iSpring's quality and pricing.

Does the job
I think it does the job in general but if you need more information on your water, you need to get somthing else. The first time I used it , it gave me different readings on the same water so I need to figure out how to use it..,

Does not work out of the box
Very cheaply made. I'm not sure the battery's dead or what the device does not turn on/work out of the box. Tried to call the number on the box for service, nobody answers the phone after tried multiple times. Horrible!

Is your water soft or hard? The answer is yours for less than $15.00
This little meter answers the question, is your water soft or hard and to what numerical degree is it so. this is a small accurate and innexpensive device one should use before committing to spending huge amounts on water softeners

Very High Quality Test Meter
I have used this test meter for many years and it is still working well. It is well made and when comparing it to other ppm meters it seems very accurate. All the ispring products I have used are outstanding quality. If you ever do have a question about installation or an issue with any product you purchased from them they are there to help! There costumer service is the best I have ever seen! Sean has helped me trouble shoot and also offered quick and easy assistance with parts and filters even when my system was no longer in warranty. You will not find a better customer service department anywhere!!

Seems to work, readings are variable from tap.
Our well water tests anywhere from 700-800 TDS. This can vary from samples taken a minute after another. I am not sure how normal this is for samples to fluctuate on the same line this way but in comparison to testing the filtered water samples from my RO faucet I have to say it seems the tester seems pretty accurate. My filtered water samples read steadily from 21-22 TDS. Store bought cooler water reads at 11 TDS from spigot. I'm giving this item a 5 star review because I have no reason to believe it isn't operating as designed to despite large fluctuations in close water samples from tap. I think as well water sits in lines there is more TDS, the longer I run lines before I take the sample the lower the TDS number readings are. This is consistent.
