75k miles in Sena headsets, countless downpours, never had a waterproof issue. Smh10, 10u, and now my srl. I've tested it up to 150+mph and still connected to another rider, running much slower. Range is usually about line of sight. Whatever they claim, just disregard it. They're not gonna reach 2 miles unless your daisychaining several together across a group. I had issues with my sena 10u, and started considering scala, but you'll find reviews with people having the same issues as any other brand.
