Sonder U is extremely light and it has a 1000mAh battery which is outstanding for its modest dimensions. The Sonder emblem on the entrance attracts finger prints but it also provides some attraction to the device. It's got a slightly rubberized finish which makes it grippy and comfy to hold. https://magazinerounds.com/aloha-sun-rodman-9100-disposable-a-new-wave-in-vaping-experience/
