300e relay OVP-2 versions,which one better?
 

Ebay offers 2 version by aftermarket KAE from 45-66 bucks US:
one looks like 3 310 210 with one fuse;
the other looks like 3 310 300 with 2 fuses.
Which one is better?
I am thinking of buying a spare one since i've heard so much about this malfunctioning.

The one with two fuses is the newer part.

Make sure the number of pins on the bottom match your car. On the one fuse ovp there are 6 pins,while the 2 fuse versions usually have 7 pins &therefore may not fit your holder.
