I had a Guner for about 50 jump and really liked it while I was jumping it. It fit well enough when I bought it that I never had to bake it. The pockets for the audibles are secure, but the padding needs to be pulled back to access them. The Velcro strips that hold the padding in place are glued to to the inside of the helmet and these tend to come unstuck with time. Not really a big deal, they can be re-glued at minimal cost and effort. I was happy with this helmet until the buckle that holds the chin strap failed, leaving me helmetless at 7000 ft watching $450 worth of skydiving gear float away(that's approximately 23 jump tickets for those that need help converting from USD). Just to clarify this is the black seat-belt type with the red release button. I was doing a solo jump when this happened so there's no way the buckle got bumped or stuck. I know I fastened it in the plane, I even felt the chin strap come undone right before the helmet lifted off my head. This is a pretty major flaw in my opinion. I lost not only my helmet, but also my audible, neither of which was cheap. For the cost of skydiving gear I expect to it perform as flawlessly as possible, not just so-so or O.K. if you make some improvements to it. If you have a Guner or other Bonehead with the same type of buckle it's not hard to replace with something better. I know someone at my DZ who did this with his helmet. As for Bonehead I haven't contacted them yet, but I do plan to. If they replace the helmet and the audible then I'll consider them redeemed. If not the I might have to avoid them in the future just on principle.
