I hesitated before ordering the product that I find very expensive (~ 16% of the price of the complete GPS!) But the comments on the cheapest products were discouraging.
It is indeed an original carrier and perfectly replaces the mine which the flexible portion of the cup was cracked (it ages badly in the sun).
It connects to the end like the original on my Tomtom XL IQ routes and sticks very well to the windshield.
