“I’ve been using Healthy Human 21 oz. Water Bottles with flip top lids (I do not like straws!) for about 6 years now and have even given many to friends and family as gifts, ALWAYS with positive feedback. I just got my new curved bottle and I LOVE it! I love the size, insulation is superior and BPA free, never been interested in the “IT” water bottles because I love my healthy humans way too much!!”
