A glowing reminder to do something a plain bottle already does.

Verdict: Not Verified
Not VerifiedThe short answer: A decent insulated bottle with a glowing puck that needs charging and an app that needs an account, to remind you of something a plain bottle already does.
- Buy it if
- Someone who tracks every metric, wants intake in an app, and will remember to charge a water bottle.
- Skip it if
- You want a bottle that works when the battery is dead — which, eventually, is most of the time.
- Best feature
- The bottle itself is a decent insulated steel bottle, and the glow reminder is admittedly hard to ignore.
- Biggest annoyance
- The sensor puck needs charging, the app needs an account, and the tracking only works if the bottle is the only thing you drink from.
- The catch
- You are buying a subscription-free app experience today; the company's pivots suggest planning for the day the app is abandoned and the bottle becomes just a bottle.

Insulation is fine and the glow is admittedly effective for a week.
