No major fault found with this product for 2 weeks of use. It sticks well on overshell my smartphone. Its ovoid aspect allows to fit more easily the right smartphone (a round, more likely to switch). I could not test the audio splitter since the helmet no longer fit into her hole with my extra shell (Spiegen). By cons, having an audio splitter, permit to dismantle the suction cup into two parts which then takes up less space in my purse.
What happiness (or almost, because of the too short for my shell connectors)
