Love love love it! I got the 1L bue and grey - the blue is vibrant and the grey is sleek and ... well just looks cool. The line tracker really does keep you in check - and for someone like me who does need that extra reminder to drink up - I found this a great way to not only log how much I drink, but I also followed the timeline to ensure I'm well hydrated throughout the day. I justified the price by considering its motivational angle and high quality. Delivery was as expected. Highly recommend this product.
