Doesn't work


For the first week everything was great. Then it couldn't recognize how much water was in the bottle and quit noting when it was going down. I reinstalled the app, reset Bluetooth, nothing was working. I checked the reviews and saw that exact scenario was happening to a lot of people. The only thing it could do right was see the temperature of the water. Over a month goes by, I contact customer service finally and they say it's a known problem and the new app update fixes it. The new app update only mentions Fitbit in the description of the update fixes. I would have tried the whole troubleshooting process again, but because they didn't want to state their app (or firmware) had a bug, for whatever reason, and pretend like each update was to account for Fitbit or new OS system, they didn't inform their consumers. Check the reviews for all versions. Majority one star reviews. Just a crappy way to do business.

Works as advertised


Recently purchased one of these to track hydration intake. Instant recognition (most of the time) of your intake between the bottle and the app. One does have to pay attention on how to use it and how it works. If you take the time, it makes sense and works well. Synced it up with fitbit and it works great. If you're not of the instant gratification genre and have a bit of patience, the apps sync as advertised and it helps with water intake and personal accountability. I liked it enough and it works well, so I bought another one. One for home and one for work, both sync and have been very helpful. Thanks Thermos!

What was I thinking?


What a useless device! I'm one of those people who doesn't remember to drink enough water. I I thought that having reminders and having my water consumption monitored and automatically entered in my food log would be helpful. I was mistaken.
1. Only one reminder a day. Not helpful enough.
2. When the bottle is emptied the consumption of 24 oz is supposed to be automatically entered in the bottle log and update Fitbit's log. Totally cannot rely on this happening. More importantly, do I really need a device to tell me that I've just finished a 24 oz bottle of water? Of course not!!!
3. Updating Fitbit does not translate to an update of MyFitnessPal. That is technically understandable, but one can infer that it would update MyFitnessPal via Fitbit.
