There seem to be a lot of 1 star reviews comparing Bubly to other drinks that are zero sugar but loaded with artificial sweeteners. There is no sugar or artificial sweetener in Bubly. The flavors are mostly an essence of the fruits/flavors they represent.
I believe water like this is an acquired taste and so much better for you than other carbonated drinks loaded with sugar and artificial sweeteners. If you know what to expect this is a great product and I'm happy that it is available!
Get the sample pack and actually give this a try. I find these taste best cold right out of the fridge. Over ice they seem to lose too much carbonation.

Wow! Love these flavors & that there isn't the strong mineral aftertaste that you get with other sparkling water brands. Definitely will put this on Subscribe & Save! Worth a try! Definitely recommend!

Edit about Flavor -
Almost with all sparkling water, I have to have a few sips to cleanse my pallet of all the strong flavors in every day life. The more sugar or sweet drinks you normally consume, the weirder this will taste. When I first started on sparkling water I hated it, pushed through the first can (of another brand) and then it got easier. The more you drink and more often the better sparkling water starts to taste and the more sickly sweet regular soda tastes. In my experience as well as anyone who has done a sugar cleanse will tell you!

I have really enjoyed Bubly. I have been trying to cut out soda for the obvious terrible implications from it and sampling the market for different zero sugar/sweetener and calorie drinks. I tried a certain home soda creator thats popular, but never got a great taste.
This sampler gives me the ability to try all 8 flavors without having to purchase 8ct packs of all the flavors. Plus, these waters being so new, my local store has had limited flavors and inventory. This comes with 2 cans of every flavor (3 of lime and grapefruit).
The flavor on these is great. I think they have a good smell, which makes your senses feel like you aren't just drinking a lightly flavored sparkling water. The flavor isn't very strong or overwhelming. The apple smells like a freshly cut juicy green apple!
All the pop tops of the cans have a little greeting and there is a pun saying in a circle on the side of each can which makes me smile. (Know any nice cubes?)
The box is came in was adorable and all the cans were safe and undented.
Can't wait to pick my faves!

Best sparkling water out there. Flavors are great and not too strong. Highly recommend the sampler since everyone I know likes a different flavor. The best (in order) are: Lemon, Mango, and Orange. I am not a Grapefruit fan, but this flavor ranked highly with my friends who like the fruit.

Just got the variety pack and have only tasted the grapefruit and the strawberry. Amazing! I have tried virtually all of the bubbles including the expensive imported ones and this kicks it up a lot! Just right carbonation, just right hint of flavor and just right price! This will be so refreshing in hot weather!
