It took me a second to figure out how to work the pods, and then I need to press down the lid of the pod onto the Gatorade bottle stopper. I really don’t see a reason why the pod needs to be inserted, as why can’t I just open it up and put the concentrate in any water bottle and then fill it with water. I thought there was a lot of waste also, as each pod is packaged in its own plastic container then you have to use their special large plastic water bottle. That being said, I like the low sugar formula, and would purchase that again. The water bottle did leak and drip down my shirt every time I try to use it, so it won’t be going back to the gym with me for long.
