They've lasted over two years on my son's car, but the same version (Latitude) lasted less than a year on my GF's car before skipping. That's not exactly a statistically significant sample, but enough to tell me that YMMV. My preference is the OEM blades refilled with silicone inserts. I order mine on eBay from several sellers in Malaysia. I pay about $8.00 for a pair. The ones on my car have done well, so far, for over two years.
A good periodic cleaning of the rubber using a paper towel and silicone (spray or brake fluid) helps keep them working well longer, in my experience.
Once the vehicle gets some years on it and the windshield has pits and scratches, which are normal, the inserts will not last as long because the glass becomes "abrasive."
