Very good, I put mine in a 23.7 oz water. A very nice flavor. Took 12 mins to completely dissolve in cold water. Bought a lot of flavors. Would like to see grape. This one is Passion fruit. It is very very good.

These taste awful and cannot dissolve fully in water. Never again.

No sugar mild taste good flavor

I think the Passion Fruit flavor is actually really good. I tried my first one in a glass of about ten ounces of water. This is less water than the amount mentioned in the packaging, so the flavor would be a little stronger.The added vitamins and electrolytes are a plus, so this might be a good alternative to the other, more sugary electrolyte drinks.It dissolves easily, without any need for stirring. It took maybe 3 minutes or so. These are easy to travel with. I didn't have any issues opening it, or popping the cube out of the package. However, there is a lot of plastic; each cube is surrounded by a little plastic case with a plastic film on top. The labeling makes a big deal about recycling and being good for the environment, so this is a bit off-putting.These are very expensive, at more than one dollar per tablet. I can't see myself repurchasing these at such a high price.

Great for hydration.

Reminds me of la croix or something similar in terms of flavor. Good, but not overpowering. The added vitamins are nice, but they're cheap vitamins that you can find in basically anything these days, so not much value add there. The price is what eventually turned me off of these. At a dollar a cube, it's just hard to justify being a repeat customer.

(Review of Waterdrop Microdrink, Hydration Vitamin Tablets)I really like these Waterdrop electrolyte hydration tablets. The flavor is unique and not overly sweet. They dissolve quickly and completely without needing to stir. And they do make me feel hydrated and refreshed. I think these Waterdrop tablets are very useful for on-the-go because you can pack just one or two at a time.Of course, the downside to this is that there's a lot of packaging. Each tablet is individually wrapped in a tiny plastic container with a foil lid. Given this, I wouldn't use these tablets every day when I'm at home but I'd save them for travel. But, they do look really cool, fun, and futuristic!

As someone who tries just about every new beverage I see at the store, I jumped on these. The idea is great, portable, single serving, no-stir required hydrating flavor cubes?Unfortunately, The idea is just about all that is good. Starting with the packaging- its horrible. The cardboard box has a spot labeled "push here to open" which theoretically is supposed to open a hole in the box so you can shake out one of these cubes... yeah that didn't work as intended I ended up tearing the box apart to get at them. The cubes are individually packaged in yet another annoying to open manner, after working my fingernail in to open one, the wrapping part of the blister pack left a little corner of plastic covering an edge which left me shake shake shaking the cube to get it out where it was eventually sacrificed to the floor gods.The second one made it in my cup. I let it dissolve for a few minutes. It was taking longer than I wanted to wait so I ended up going to do something and came back like 15 minutes later to find the cube had indeed fully dissolved (save a couple floating chunks) and my beverage was ready. I took a big sip and ughh first thing I noticed was the unmistakable funk of stevia. Lots of stevia. They're advertised as sugar free but I should have played closer attention to the ingredients. At least its not aspartame but I wish they would have been more up front with the stevia content. So there was a hint of maracuja flavor, but mostly it was just overpowering stevia. Not what I would call hydrating or refreshing. 90mg of sodium also kind of seems like a lot for a cup of water- that's more than a bottle of coca cola. And as far as hydration goes... some real sugar would have been much more welcome than STEVIA. A little bit of sugar is GOOD for hydration. It also does not contain any zinc or magnesium as one would find in pedialyte or gatorade.Now, if you LIKE stevia, and HATE plain water, this might be something you would be interested in... but at nearly $1 per serving at time of writing, I feel like you could find a better option.TLDR; annoying packaging, doesn't taste good, not refreshing or hydrating.
