My experience with these has been a positive one. They seem to be very similar to my VTC 5's and id be hard pressed to tell a difference in a blind test. The VTC 5's I have seem to have a little more initial power but my efest 35a seem to last a few minutes longer. So close its really hard to tell.
I am waiting on 2 full size nautilus tanks.
Thanks for the feed back. I'm going to be running them in my sigelei 30w for the time being but have been looking into getting a mech mod for use at work and thought they would be good for that as well.
