I ran the Abom HEET all last year, we had extreme cold during the first month and I found my Heet were not keeping up, their customer service was great and I ended up working closely with them to dial the goggle in, they can actually program the goggle and change the heat mode, the balance is then battery life.
The program they are putting out now works great, I also have a pair that will run at max but battery life is only 4-6 hours.
I'm not a fan of the huge battery on the Oakley but fact is it works.
One key thing for me, the lens in the Abom is amazing and second to none in my opinion so you end up with a goggle you wear all the time.
I have three lenses, all have clarity over my Klim, 509 and Dragon.
