These taste ok. I like the blueberry, that's my favorite. A bit pricey, but these things work! After placing one in my water bottle, I can REALLY feel the difference! Helps with that tired feeling you get when you aren't drinking enough water. Great for older folks who don't like to drink plain water. I will definitely purchase again and hoping the price drops a bit.

One tablet packet would be fine, grapefruit-ish, the next would be"...huh?" It's like bad Quality control in the flavor mixing profile. This third tablet packet taste like something of when all the ice melted and mixed with the remanence of the drink, I think this time orangie-ish. All from the same box. Yeah, will not buy anymore.

Tasteless, zero grapefruit flavor. Very disappointed. Cannot return.

I love these. I drink my water with one of these cubes before/during a workout.

Just tried this in 14oz of sparkling water. By the time the cube dissolved, the water was flat. Went to drink it and no flavor. Very disappointed.

This is my favorite flavor! I will say that you have to like grapefruit, because it actually tastes like grapefruit, not just a generally fruity flavor. I love it!

Not much flavor with the grapefruit drops

These things are NASTY tasting. None of the supposed flavor, just nasty raw powder vitamin tasteI wish I hadn’t bought them, I totally wasted money!!
