Have had this helmet for 5 years now, been through several sets of batteries and many shields and haven't had a problem yet. I even managed to cook and warp the unit and it still works flawlessly. I've noticed other auto helmets aren't fast enough, run a couple beads in a speedglass and I get a flash spot in my vision. Not in my beautiful Jackson though! 4 arc sensors and intelligent arc sensing pay off way more than you would think, and the amber color gives great visibility. I can run a shade darker than my co-worker's helmet and still see where I'm going.
Pros-Comfortable head strap/clamp (whatever.
-Light flexible helmet
Cons-Batteries don't last forever
-Easy to cook it (I get close)
