Yeah it's brand new. A guy at work is getting one and I asked him if he knew anyone that'd used one and he said he'd just read reviews on some backpacking websites.
The Reactor was far better then a Jetboil (that's the wind blockers big brother), so the WB is more a comparison to the Jetboil SOL......as far as weight.
Either the JB, Reactor or Windlocker will be fine for most applications, but the Reactor is the most durable and the Windblocker is the best all around between the 4 of them.
Thanks guys, I figured not one had used them a bunch and had a tough time finding any good reviews. I know the jet boil is a great product. I'll look more into the reactor . Thanks again
