The Starter kit with micro teas was the third Waterdrop set I have purchased. I was a bit hesitant on whether I would like the Microteas being a dedicated black Rooibos drinker but I am pleasantly surprised to find that I do. I love the wide mouth steel bottle and find it easy to carry around with me. As the drink stays hot for hours, I find that I am definitely drinking more water. I previously purchased a Microdrink set and love the subtle fruit flavours, especially Youth. I always carry a few Microdrinks around with me for top ups during the day. My other set is a borosilicate glass bottle with a Neoprene sleeve which has a handy finger loop for carrying around. I would highly recommend all products.
