Review on Wacom Bamboo Ink Plus: The Ultimate Smart Stylus for Windows Ink Enabled 2-in-1 Devices by Chad Carter

Works but the battery drains very quickly even when not in use, after 5 days the battery is full empty. Bluetooth, Windows shows a battery gauge, but it doesn't update unless you turn it off and pair again, so you can't know how fast the battery is draining until it stops working without warning. Suggestion for future models: 1) longer battery life 2) different colored LED showing remaining charge 3) some kind of real-time battery updater app
