Simple replacement for my Subaru 2017 Impreza's rear wiper blade insert. I did not want to use the stock rubber replacement and so upgraded to silicone. It wipes good but the replacement insert has a reinforced stop area, this area is best used for the bottom of the blade housing as it prevents the wipers edge from hugging the curvature of the rear glass if used right side up. This is about 5mm or 0.5" of missed wipe only at the top of the blade where the curvature of the glass starts. I changed the orientation and the blade insert and performs like a new stock rubber.
