Taste:  I really like the strawberry lemonade, lemonlime, and grape.  I didn't try the berry or punch.  I couldn't tell the difference in the sugar free, lite or regular taste.  The sugar free wasn't bitter or anything.  

I like the liquids because you don't have to wait on the sugary stuff to dissolve.    ACtually I wouldn't wait for it to dissolve I just chugged the water with the sugar undissolved.

APparently it comes in pouches for making large batches etc, but for fishing I think the most convenient is the squirt bottle of sugar free.  It has 24 servings and takes up verry little space.  I just kept the squirt bottle in my boat cooler with the water bottles. The packets aren't quite as convenient in the boat.

THey really seemed to work.  Terry and I used them on practice day - 95 degrees, little breeze, 9 hrs on the water and on tournament day, 102 degrees, little breeze 8 hrs on the water.  Never felt dehydrated, no cramping etc, not even that night.  

I typically drink Smart Water (water with electrolytes/no flavor/no sweetner, etc) and have great results.   Squincher performs just as well.  I would probably only switch if it was economical.
