I like Poland spring water was they have no aftertaste like other brands. Also, this is spring water as apposed to "filtered" water which is basically sink water. These bottles are mini size and easy to take with you wherever you go. They also take up very little space in my bag or fridge. I buy these only when Amazon has them cheap. Problem is that pricing is always changing. If you get a great price, just stock up on it and you won't regret it!
