BlackIce Pro or Extreme Rev2
What is the difference between these two? Does anyone know where I can find a comparison?

Thanks.

The Black Ice pro is rated for 360KCal per hour (1428 BTU per hour) or 418W, the Black Ice Extreme is rated for 790KCal per hour (3134BTU per hour) or 919Wh.

Therefore the Black Ice Extreme is better.
