What's your approach to picking the right smart water glass?

A little over a year ago, BluFit ended in failure on Indiegogo, raising only half of its goal at the end of the period.

BluFit's lid contains a Bluetooth chip, water sensor, and rechargeable battery that lasts for 7-10 days.

BluFit's functionality is no different from other crowdfunding successes, but it loses out on design and experience. Both the UI and the kettle's "waist" shape are not refined enough, and the color scheme is messy and unfocused. In addition, the kettle as a little attention to daily necessities, once a few times due to lack of power and can not be used, a second to lose the aura of intelligence.
