Very nice all in one water meter, maybe not so accurate, but it's work fast and multifunctional, good.

At Aliexpress most of the sellers have a good sense of commerce but some others have no regard for the customer. This is the case with Yago Technology LTD. France is not an underdeveloped country and yet Yago seems to consider it as the third world. Curious technique of accusing the local post office of non-delivery of the product rather than researching where it is, or proposing an arrangement. For Yago, if a customer is unhappy it doesn't matter, there are others! Curious business methods. Here is a supplier that I will avoid in the future and I strongly advise to do the same if you want to be considered in case of dispute.
