Rated 1 out of 5 by from Horribe Taste for Lemon Lime GU made a cheaper hydration tablet compared to other brands. Having used their GUI packs for cycling, I figured I could not go wrong. Well that was a bad assumption. I took this tube with me on a 40 mile backpacking trip. Arrived at my destination for the day (13 miles in) and need to rehydrate. Followed the instructions and gave it a try. I could not finish half of it without tossing it out. It was bitter and horrible tasting. I was very disappointed. Will be putting the tube in the office labeling "free" to anyone else who wants to give it a try. It was so sour, not pleasant at all, and very little flavor to it.

Rated 2 out of 5 by from Leaves a residue that is hard to clean. This product tastes okay especially when compared to other electrolyte drinks. The tablets are very convenient and they dissolve fully. However, unlike the previous version, the new tablets leave a residue that can be very hard to remove particularly if the tablets are used repeatedly. I am extremely hesitant to use this product in anything that would be difficult to clean -i.e. a hydration reservoir for a backpack.

Rated 5 out of 5 by from Savin my butt this summer Since I work outside, I started this year drinking just my normal amounts of water. The first real hot days we had really drained me and even though I took in plenty of water, my body needed something else. I've used these while ridding and mix one in my water bottle when I swim. So why not use it on the hot days at work when I'm trying to stay hydrated and alert. It really has worked great for me this summer. And for the cost, it beats buying gator aid style drinks all day.

Rated 1 out of 5 by from New Formula Is TERRIBLE! Been using GU Brew tablets for a long time. Went to restock my supply and found these new ones. Without any concerns, I bought 6. Tried one that night and UGH! The tablet looked and tasted like sawdust. Horrible flavor. Took them all back. So upset. Now I need to find a new electrolyte product.

Rated 5 out of 5 by from completely disagree with the "1 star" review I do long distance triathlons and always using stuff like this. The great things about the tabs are (1) they travel easily, (2) don't have to measure when you're on the go, and (3) contrary to last review, they dissolve easily when mixed with the proper amount of water. I also particularly like this flavor as far as energy drinks go.

Rated 5 out of 5 by from Good Alternative to powedered Gatorade The GU tablets are a great source of electrolytes. After drinking water all day on the AT, it is a great feeling to get some flavor into your body. I used to carry powered Gatorade to do this but the weight difference in your pack between these tablets and the powder is huge.

Rated 5 out of 5 by from Kept my Wife's legs from cramping Bought these to have some electrolytes just in case. My wife was having some cramps on a 15 mile hike in Big Bend National Park March 25th -the last part of the hike was pretty hot - these things worked wonders in providing needed electrolytes
