## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product.
*by A***A on 17 October 2020*

Great product. Good price. Nicely packed. Used few times to check the purity of the water as I drink only purified water. Also Used to check water pH. Everything works well.

### ⭐ Failed instantly, poor design makes it impossible to avoid filling up with water.
*by S***Y on 6 August 2020*

Tested in the provided pH 6.86 buffer solution. First measurement was spot on, second slightly off, then quickly very worse to the point that tap water was measuring pH 1.5!The electronics circuit board is completely exposed by large holes in the rear of the pen, so when you rinse the electrode any tiny splash will get inside, I think this is what killed the device. You cannot dry inside the product without destroying it.

### ⭐ Terrible - don't buy
*by S***E on 6 July 2022*

Thebprodct worked perfectly for 2.5 months then that was it oh tester stopped working followed by the second a week later.Now I'm passed the refund period or gettting a new one.
