I grabbed a set of replacement wipers a few days ago - RainX "perfect fit" in the sizes specified in the manual for the front wipers (18" and 26"? Can't recall at the moment).
The install went just fine - wipers aren't exactly rocket science - but the new wiper housings *don't quite clear* the upper part of the wiper arm where the position sensor and fluid spray nozzle live. As a result, the wipers are super streaky because their being pushed down on one side by the nozzle assembly.
