I ordered in Chinese New Year, everyone rested, but after the holidays delivered very quickly, the seller is sociable and friendly. The product looks good, there are no batteries, so I will check and additional feedback later.

The order was issued and sent within three hours! Brought on the 4th day! The courier brought home! Packed very well: a box, a cover with a zipper, a navel. After testing, I will add a review.

Great device. Everything works. A little only the screen on one side is slightly recessed into the body. Maybe marriage, but otherwise there are no comments. Delivery lightning. 14 days to NSC

I came quickly. Works, looks reliable. Of the minuses: the incomprehensible circuit of installation of batteries and instructions is not Russian, how to calibrate I also did not understand.

This pH meter looks very tough and durable, the package is protected undamaged, super fast shipping time see photos like professional equipment.
