The WOO 3.0 case (Former Frequent Flyer Case) is still not water proof. WOO 3.0 Hardware still keeps failing due to contact corrosion. And yes, I had washed and dried it before charging. Just had to replace mine again.
Any modern smartwatch, smartphone or electric toothbrush has the ability of wireless charging. This technology would solve the contact corrosion problems and at the same time eliminate the need for the flimsy case that tends to brake easily or snap open on hard impacts resulting in device loss.
The new mount also needs to be simpler and operable with one hand. I want to unmount and remount the WOO while flying the kite when changing boards, e.g. from Foilboard to Twintip. The best and most simple mount that worked very well was the first (1.0) one with the slider + release button instead of the rubbers. It unfortunately was abandoned due to the corrosion and breakage problem. With wireless charging and a resin filled, 100% water tight WOO Unit, you could revisit this design and also improve on and re-simplify the mount.
