What a fun product. My daughter needed to monitor her water intake. This tracks it and encouraged her to drink more. It was the perfect Christmas gift! What a great solution! Love the lighted bottom. My son and daughter have diferent light settings and have really enjoyed using them. I highly recommend them for the techno savy young adults!

This is a great way to know how much water your drinking, I honestly didn’t know until I started tracking it with this cup. I gifted these cups for all of the adults in the family and everyone seems to like them.

Works great! I'm usually ahead with drinking water, so I don't get too many reminders. Though when I do, it's very noticeable.

I’ve been using Hidrate spark for years and have several models. The drink up reminders and tracking help so much with staying hydrated, especially if you’re tracking for weight loss.

Gave as Christmas gift, recipient says not worth cost.

Returning. Doesn’t do a very good job at keeping beverages cold or hot. Sometimes it illuminates and sometimes it doesn’t, when time to drink.

I was so excited to do a daddy daughter water project after his blood tests, and keep track of his H2O intake. My bottle didn't work 😕 My phone kept wanting to optimize the app for all the background use but it wasn't tracking my water intake. What was it doing? Tech support emailed me instructions for resets I performed before contacting them. Validation at least, but the puck is a dud.

We have bought 3 of these and after 2 Months they no longer track the amount of water we drink. So disappointed.

It looked like the box had been opened before, and there was a thermal sticker on it that said it had been repaired. I didn't pay for a refurbished unit, I was expecting a new one. Disappointing!

I absolutely love this gift I got from my mom and sister for my birthday in November but it quit working by December 25. Now I can’t find a way to get a replacement battery or return it to Sam’s Club where they bought it just such a disappointment because I really liked it.
