I like the Bosch best also.I've switched all ours over to beam type (cars and the truck). I think the brand on them now is Bosch but I'm just a big believer in the beam type. They cost a bit more but work as winter or summer blades and hold up well for us.
I too use Silblade wipers and have for over 15 years. The longest lifespan I have experienced is 8 years - badly distorted, permanent "parked" lean to the blade, but they still worked fine!
One note, make sure you get the traditional, metal framed version, not the molded or extruded plastic frame versions. I put two sets of the non-metal-framed Silblades on two vehicles in 12/2013, and they all failed by 6/2014. It appears that these versions have a much thinner connecting web between the actual silicone blade and silicone base (which is captured in the frame). Each blade separated at this web, at each end of the blade. Amazon refunded both purchases!
Yes you did something wrong. You moved to a desert! I used it in other parts of the country and yes it can be a mess. The trick is to scrub your windshield with bathroom cleanser like Bon ami or Comet cleanser. Follow up with the best Windex job you have ever done. The next trick is to put on as light a coat as you can and let it dry. Buff the hell out it to get as much as you can off. Basically it's more work than is worth doing unless you live where you scrape ice off of your windows in the morning. It's amazing in icy climates for that morning scraping ritual. Best blades are Anco hands down. No quality control issues and cheap as dirt. Most won't dare buy the cheapest blades but they are the best. Walmart, cheap and work the best.I hate rainx. It always smears way too much for me, maybe I have been doing something wrong?
