Hidrate SparkPRO 20oz Insulated Stainless Steel Bluetooth Smart Tumbler, Brushed Stainless Steel

Works well

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.

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, like everyone else, have been told how important it is to hydrate. I thought I was doing a good job until I bought this. Big difference when you completely hit your goals and this tumbler reminds you all throughout the day with flashing colors. Pairs with their app that in turn communicates with Apple Health. Fantastic!

Cheap for the buck
