We reviewed Tea Drops on this blog in 2014, when they were still in the developmental stage and just introduced to the market. To Nancy, they were 'too sweet', and to Susanna, 'oh that's good, they taste like candy' which is pretty much the review we give them again in 2019. On their website, they do have a product that does not include sugar, so they are attempting to meet the demand for something without added sugar.
Tea Drops are fun and convenient and easy to use. Just be aware that they are sweet.
