Who knows Wipers and refills? Especially originals

Comparison and Review of OER's K164R Wiper Refills:

The Good: They fit and at least in this afternoon's light rain, they worked well.
The Ugly: They are ugly when compared to an Anco 12-15. But few people will look this close and you get to keep the cool push button blades your car came with.

So the OER is a reasonable alternative for a working car keeping the original blades.
For 100 % concours, or any serious points type originality competition, these won't cut it.

The Installation:
The old Anco and presumable old Trico LP refills can be installed either direction. The raised center holds the refill very securely.

The OER K-164 replacementseems to be directional.
What worked for me was installing the notched part of the metal rib into the fixed retainer on the wiper.

Not so bad!
Maybe not quite as bulletproof as the original style. But its nice to have fresh rubber on the glass.
Compared to the price of old stock refills of unknown condition, the OER price isn't bad. Overall it seems to be a good alternative.
