I chose the rear window wiper arm + for my Seat Ibiza 4. The mounting system being the same, it is adaptable. The product is solid, however, the texture of the plastic is a bit rougher than on the original model (with Seat), but given the price difference (we go from here 17 euros to 40 euros), no to quibble.
The only gripe is that the windshield wiper was slightly cracked on an edge (but without affecting the operation). Therefore satisfied by the quality / excellent price.
