Functions well, compact size. The hold feature is essential. Excellent price. No complaints. I am surprised to find out how clean (or unclean) various water sources are. I bought this to monitor our under-sink Reverse Osmosis filtration setup. Clean water is wonderful, this meter lets you know how pure your water is.

I've used this on a few sources since buying it a few weeks ago.

Suburban Philly tapwater: 230 ppm
Same water but filtered by the fridge: 200 ppm
Dasani: 30 ppm
Grand Cayman tapwater: 175 ppm
Le Bleu delivered water: 0 ppm

Needless to say I was shocked by the Le Bleu but it really re-enforced the value of paying for purified water. I know the Dasani might actually have some good things in it (magnesium, potassium, etc) but I would definitely recommend getting a tester like this and finding a way to get water (delivered, RO filter, etc) which is pure. It's a small price to pay to independently verify the purity of the water you're drinking. Rating: 5 / 5

Nothing fancy. But it does what they say it does and it’s a reasonable price

Don’t know how accurate it is but I like being able to test the water I’m drinking be it a resturant, public water fountain or cold mountain stream.

It was less than what I expected but worth the price.

Delivery was timely.
