How Useful Are ORS For Daily Hydration?

I am going to my kitchen this morning. I see a packet of ORS on the counter. I pour it into a glass of water and stir. The powder dissolve quickly and the water look clear. I feel curious because it look simple but taste a little salty. Some tiny bubbles rise on top.

I am thinking why ORS is popular now. People dont just drink plain water when feel weak or dehydrated. I feel curious because some ORS taste good but some feel too strong or bland. Maybe flavor and mixability matter more than brand. It make me wonder if all ORS are same or some are really better for quick hydration and energy.

I take my phone and start checking while scrolling many online marketplaces including alibaba. I see ORS packets in many flavors and sizes. Some small single serve some big multi packs. Some fruity some plain. I read few reviews where people say some ORS work fast and easy to mix others leave clumps or taste bad. It feel like picking right one really matter if you want fast relief and easy use.

Now I am thinking which ORS are really better for daily hydration and quick recovery? Are small flavored ones more usefull or big plain ones better choice?
