I'm in Wisconsin and have been using neoforms during winter for 3 years now. They're not miracle workers just like any wiper blade, but they are much, much better than framed wipers in the winter. I'm fairly abusive to them because I rarely clean all the ice off the glass nor wait for the defroster to melt everything...lots of neoforms scraping on ice situations in my world. Anyway, they usually are fine during the following spring and summer. More than anything the direct summer sun and heat is what kills them over time...much more than winter. I will state that I replace them in the fall so they're fresh for winter.AltimaJA10 wrote:I made mistake of buying replacement blade at dealer (Nissan part WBILL-NIS28F). What a cheap-looking POS. Did not match the stock blade's aero look at all. Took it back to dealer parts dept & suggested they share my feedback with corporate wonks. Ended up trying those Neo-Forms. Worked great in today's rains, but holding judgment on durability & winter performance.
