HidrateSpark PRO 20oz Insulated Stainless Steel Bluetooth Smart Tumbler, Brushed Stainless Steel

Works well

Ótimo produto ! Muito bom

It took me awhile to get used to setting the bottle down after filling it and before I took a drink. Also took awhile to get used to charging it, and recalibrating it on occasion. But, it has been worth it. I have had it for a year and a half now, and 560 days in a row I have met my hydration goal. I've seen a huge decrease in the number of and severity of my migraines, my skin isn't as dry, I don't feel awful after working out, and my sinus pain during the winter is pretty much gone. I remember I felt really silly buying a high tech gadget-y water bottle with an app just because I couldn't remember to do the basic human function of drinking water, but you know what, I'm over that. This thing has solved a life long problem for me that had made so many other things in my life better.

Imagine buying a luggage scale only to arrive at the airport and find out you have to pay extra because your bag is actually several pounds heavier. If I buy a product that's supposed to measure, it needs to measure accurately, or as with this product even measure at all. I never tested its accuracy down to the ounce because it often failed to detect when it was filled or emptied. The documentation is non-existent, and you have to recalibrate it every time you remove the sensor puck, I happened to stumble across this fact in the FAQ on the website when I was trying to figure out what the glow patterns mean. The usability is poorly designed. Most devices show orange while charging, but this one flashes green intermittently. Each time you recalibrate, you have to inform the app which bottle you're using. The app doesn't display battery life or bottle fill status either. You don't get notifications reminding you to calibrate when the puck is re-attached to the bottle. I could overlook some of these issues, but I can't trust a product that inconsistently measures my intake. It’s supposed to flash a glow pattern when it works, but that rarely happens, because it did not detect that it needed to measure. You end up lifting and setting it down repeatedly hoping it would, just it doesn't, but then several hours later it suddenly does detect a drink. It's much easier to just write down your intake than to rely on this cup.

I’m loving this bottle! It works very well. It’s surprisingly accurate. I work a desk job and so I keep this next to me on my desk all the time. If you’re not in a place where you can set the bottle down on a hard surface after every sip, it’s not really going to work. But at a desk job it’s spectacular. Only reason it’s not 5 stars is because the app is a little basic and the $15/year to be able to get a made up hydration score and change the colors of the LEDs is pretty stupid.
