A good device, but delivery is a nightmare!!!! Tracking on some very left tracker, on the way 93 days. The seller is silent as a drowned. If not for the absence of a normal tracking, then everything would be on the money. |

Delivery of the order is very long, more than 2 months and what is the worst that the defective device was sent. Water quality does not measure, constantly shows zeros, apparently, the calculation was which is nothing to compare with, but I had another such device, and this one took as a gift, so I checked both devices with water and it became clear that one device, constantly showing zeros, not working .... What's more, ordered complete with the device 2 batteries from the same seller, he put one in the order, hoping, probably, that while the second battery will be found, time will pass and you will not open a dispute. But everything was at hand, checked everything and found out the trick of the seller. Opened the dispute, for the battery second immediately agreed to return the money, apparently knew that I sent not the kit, and for the device itself-I expect the decision of AliExpress! If the decision is not in my favor-I will add feedback. Do not recommend this seller!!! |
