It looks very good and works, but my dissatisfaction is that the description in the pictures shows that there should have been a leaflet in the box, which is nothing more than the empty box. This was very good for documentation and correct usage. For quality, it deserves 5 stars, but because it does not have the leaflet, although it appears in the picture in the description, I cannot give the maximum mark as the product deserves.

Unfortunately there is no manual included

Very useful! I recommend.

Works as it should

A bit late

Is working

I was really looking forward to this device for measuring water quality. I received it and immediately checked the water that flows from the tap and the water after purification with a double osmosis filter. Result: tap water 471 mg/l, water after purification 251 mg/l. I am very pleased with the device itself. Thank you. I recommend for purchase.

It shows as if it were true, 90 ppm Morshyn mineral, 450 ppm from the tap, and 0-8 x10 from the well, which is probably very bad... it is surprising that rainwater is 014 ppm

No batteries!!! Although the description says that the batteries are INCLUDED..... Oh, there are batteries!!! They are at the top of the device!!! 👍🙏

I received the package. Everything is whole. Everything works. Thanks to Joom and the seller. The battery is inserted, it measures the temperature and hardness of the water.

Thank you received - I already have it and I want to convert this one to measure urine - check my tests, it will be miraculous

It works, tap water 209, filtered water 188, distilled 04, thanks to the seller and juma

I just received it, I can’t say anything, I have to figure it out, there are no instructions!

According to the indications, the softest water is obtained - it is boiled from a kettle ...

Haven't tried the tester yet. Hands do not reach. And so all is well. Works.

Unfortunately, the device does not work - one indicator in different waters

Shows everything correctly checked on different water sources.

The product corresponds to the description. Without instructions, but with batteries.

I received a water tester, but I still need to figure it out.

It doesn't work, maybe you need new batteries? So sorry

Thank you for a quality product.

I recommend

Everything is ok
