Hidrate Spark PRO Smart Water Bottle – Tracks Water Intake with Bluetooth, LED Glow Reminder When You Need to Drink – Straw, 21oz, Abyss

Absolutely useless device
Connection with the bottle is constantly lost, and there is no message about it; the bottle needs to be reloaded. Data in the application is reset almost every day; it is impossible to track it.For example, their application shows that I have drunk 141 ml of water so far, although if you look at the Hourly Goals, there are about 2 liters. Yesterday I drank about 3 liters of water, but for some reason this afternoon all the data was reset to 1.2 liters.

Stopped Working
The product was good then stopped working. Battery stopped working, did the reset, nothing! Amazon was not able to do anything past 30 days. They told me to contact seller, which I did. Amazon said it would fall under the warranty yet when I contacted them they refused. The battery at the bottom ended up being loose and not connecting to charge it. Will not buy again. Can’t even use warranty on a $60 water bottle.

Do NOT buy
It’s a solid water bottle. But that’s about it. Imagine you get a bottle for +50 bucks and then you’re expected to pay per month subscription in order to change the light of it through the app. I actually thought it was a joke.This is basically a bottle with a scale in the bottom. If you finish your water, you have to put it down for 10 seconds to let it synchronize, before you can refill it, then again put it down 10 seconds to again let it synchronize and then continue drinking, otherwise it won’t get logged. To finish it all off, you have to finish it all off by putting it down on a flat surface. This means if you’re commuting or using a backpack, forget about the ”smart” feature of this bottle.The idea is good, a digital bottle. However, price-performance is totally off. I’d return it, but since I brought it to Europe, apparently that’s not possible since it’s bought in the US.Charging cable is very goofy. If the sensor isn’t waterproof anyway, just put a usb c port and close it with a lid. If it works for a GoPro it should work for you as well.Bottle is okay but definitely not worth the money. A lot more R&D and redesign has to be done before this will actually become a useful product. Design is made for an office setting only. If you’re actually outside and need to refill your bottle during the day, this is useless.
