So the 42°C summer and -20°C winter finally got the better of my wiper blades today. My wife and a colleague of mine had both mentioned seeing ads for Rain-X Latitude blades so I thought I'd give them a go. They're different to normal wiper blade replacements in that they don't have the usual steel frame with all the hinges and pinch points. Instead they have a solid but flexible frame with the blade attached to it, and the whole thing is pre-bowed into a curve. That means (they say) no pressure points and a better contact all across the blade. From my point of view it means no snow and ice jammed into the hinges to freeze the blade into a useless shape at low temperatures. But being May, I'll have to wait a few months to see if that works out. They also have a small aerodynamic widget on them too which will allegedly prevent aero lift at speeds.
They snapped into place with the standard 'J' connector with no problem. I tried them on a dry windscreen - a good test for new blades - and they swished back and forth without a skitter or twitch. Trying them with the washers worked nicely too. We're expecting rain for the next few days so hopefully I'll get a chance to try them in anger.
We'll see how well they last and perform but they certainly look the part. They cost about $6 more than regular replacements.
