Like it.
I like it. Definitely salty. I look forward to using it in just water. You can add it for more flavor less water less flavor more water to your liking or add it to anything you’re drinking for your recovery or during your workout. pictures are so you see what size you’re getting that’s always deceiving.

Excellent for long runs, rides, or hot weather training.
If you’re looking for a flavored electrolyte powder that’s fairly clean, effective at replenishing key electrolytes, and more enjoyable than plain salt water, the Salted Watermelon flavor from Formula 369 is a strong choice. It balances taste and function reasonably well.

Flavor is good not too salty.
Flavor is enjoyable. I got it because it made the carb formula more tolerable. Good on its own too.

Great electrolyte mix
The one star review must be a competitor. This stuff is great on its own and goes nicely with the carb powder also by these guys. Staves off cramps and lasts a long time, think those salt packets you buy at Costco but for much cheaper and you can tailor your dose. I do lots of endurance sports and am a salty sweater so I need a ton of it. This stuff is my go to in watermelon, about to try peach now. Strongly recommend.
