The Waterdrop glass bottle I bought is absolutely beautiful, and very robust. I'm so glad to have a drinking bottle that's not made of steel or plastic, because I hate the taste of them. It goes around the house with me everywhere and is genuinely helping me drink more water, from the moment I wake up to bedtime! I'm really glad to have the (also beautiful) matching neoprene sleeve for when I take the bottle out of the house. I've really enjoyed trying all the flavours in my sample pack, too. The drops dissolve brilliantly, and the variety of flavours is really good. I have to mention the incredibly attractive packaging of the Waterdrops and the bottle, too! I know it doesn't make a difference to the taste, but it does make a big difference to the whole experience.
