You definately need to try these babies out. I was quite satisfied with my autos also, but once I tried their manuals, WOW! The manual passthrough is a beast! I can't even imagine that the expensive mods people use to boost the 510 or 901s can top this monster! And the extra long manual battery is wicked good! Seriously, you just have to try it!
And no, it never stops! But I'm ok with that!
