H2OPal Smart Water Bottle with Hydration Tracker - Reminder for Daily Water Intake, Leak-Proof & BPA-Free - Perfect for Gym, Office, and Outdoor Activities

I would actually give it 3.5 stars. Let's face it, it's pretty cool to have a bottle track your water consumption as you drink and not after you've finished the whole bottle as some do. The software needs some work though. It shows the bottle still has water even when it's empty. I have to close and open the app to get it to update sometimes, or leave the app open. There are long delays in getting help from the support staff. In short, I feel like the product is still in development. I like the concept but the execution is not where it needs to be to warrant a true 4 or 5 stars yet.
