Voltage Regulator

I have had several VRs on different cars go bad in recent years, some bad right out of the box, some lasting only a couple months.

I found this, and wondered if anybody here has tried one? Good, Bad, or Ugly? What's your thoughts? Thanks.

I have one but without the fin. It's been working fine.
