I have been using the tracker bottle for a number of years, I have had every colour! Everyone is my house is a massive fan, me and my son have the heat insulated pots which come in handy for pack lunches, and I purchased the dog water bottle which my puppy loves.
With the tracker bottle I love the quotes written on them very encouraging to get your daily amount of fluid in!
I have recommended them to many friends, everyone in my house use them!! The time being on the side is very helpful in reminding me to drink enough.
None of the products leak, I absolutely love them!!!
