@ airport - one way or another, mostly everything is made in China ... if you're lucky, it can be Thailand ... ... seriously though, I've never had any problems with purchasing equipment directly from china, and you would be surprised that they care for the customers more than the european sellers do (pre & post sale) ... event if the purchase is only 5€ ...
I have a friend who has installed aftermarket parking sensors made in China, what is right that was happened on another brand of car and has a few inches error. It is true that the Chinese are making good products but i don't no-name made in China.
The problem with china products is, you have an USA/EU original that is usually the best there is (with a matching price tag) ... then you have a brand in china that makes an equal or almost equal product, that's usually much cheaper ... and what happens next is, you have smaller companies that copy the second, the second gets copied by the third ... and, the quality drops ... and, if you're unlucky, you'll get tuck with the mid or low quality products ... whic in turn try to be sold (by estern sellers) for as much as possible ... summary: we have a global economic crisis on our hands ...
Anyways, back on topic ... is the OP asking for the rear, front or the complete set of the sensors (and the matching interior equipment & wires) ?
I have quite a bit of Chinese kit scattered around here - this laptop among other stuff, but the stand-out bit of Chinese stuff is this, bought a few years ago and vastly exceeds the Japanese item it replaced which I still have but rarely use now. I'm actually listening to the singer in the signature on it
It was far from cheap but is able to equal the performance of competing ones costing more than ten times what I paid for it, so I am more than happy with it
