Haofy Water Electrolyzer, Quick Water Quality Test Pen, Portable Accurate Water Quality Testing Equipment for Drinking Water, Aquariums, Pools, Spas

This works so well, made me realize how gross tap water is and I have never drank it since I used this to avoid the metals and fluoride in it.

Perfecto y gran calidad.

Good

Trash here in the US.. it didn’t come with power adapter which makes it into a nice paperweight.. if you live in the US don’t Buy this POS, if you do get the adapter bc they won’t tell you it doesn’t come with one.. real shady practice..

El producto llego bien y a tiempo.

Works great was ar

This device showed me the difference between my tap water and bottled water very quickly. Showed heavy metals in my tap water!

Buen material pero se daña muy rapido

Je n’ai pas pu m’en servir j’ai du recommander un autre testeur avec la bonne prise correspondante pour ce le Canada

i will be keeping this item and waiting to get back to EUROPE to use it as the stupid plug is not for Canada, but it was sold in Canada... can you imagine, and it is my fault for not seeing that??? who the hell sells something that literally does not work in Canada with the wrong plug ENTIRELY then asks how i am doing? clearly i am irritated and annoyed. NOT COOL
